How to Throw a Slurve: Grip, Mechanics, and Drills for Every Level

Last updated: March 27, 2026

I have been throwing a slurve on and off for almost two decades, and after coaching hundreds of pitchers from Little League up through the college level, I can tell you it is one of the most misunderstood pitches in the sport. People hear the name and assume it is just a sloppy curveball, but a true slurve is a deliberate hybrid of a slider and a curveball, designed to break sharper than a curve and bigger than a slider. When it is right, it freezes right-handed hitters and buckles their front knee. When it is wrong, it floats in like batting practice and gets crushed.

In this guide I will walk you through everything I wish I had known the first time I tried to throw a slurve. We will cover the grip, the arm slot, the release, the spin profile, drills that actually transfer to the mound, the most common mistakes I see, and how to sequence the pitch in real game situations. By the end you should be able to walk to a bullpen with a clear plan, not just a hopeful grip.

What a Slurve Actually Is

A slurve sits between a slider and a curveball on the breaking-ball spectrum. Slider velocity in the major leagues now averages around 85 miles per hour, while curveballs average roughly 79. A true slurve typically lives in that 78 to 84 mile per hour window for a Division I or pro arm, and somewhere between 65 and 75 for high school and travel-ball pitchers. The shape is the giveaway: more vertical drop than a slider, more horizontal sweep than a curveball, and a tilt that lands somewhere between one o’clock and three o’clock for a right-handed pitcher.

The pitch fell out of favor for a while because old-school pitching coaches considered it a “lazy curve.” That perception has shifted. With pitch-tracking data from Statcast, Rapsodo, and TrackMan now widely available, we can see that slurves with 2,400 to 2,800 rpm of spin and 6 to 10 inches of horizontal break can be elite swing-and-miss weapons, particularly against same-handed hitters. The slurve is back, and it is back because the data finally caught up to what some of us were already throwing in our backyards.

Slurve vs. Curveball vs. Slider vs. Sweeper

Before I show you how to throw one, you need to understand what makes a slurve different. I get this question constantly from young pitchers who already have a curveball or a slider and wonder if they should add a slurve as a third breaker. Usually the answer is no, you should refine what you have. But understanding the differences will help you choose the right pitch for your arsenal.

Pitch	Velocity (MLB avg)	Horizontal Break	Vertical Drop	Spin Axis (RHP)	Primary Purpose
Four-Seam Fastball	94 mph	4-7 inches arm-side	10-14 inches less than gravity	12:30	Strike one, climb the ladder
Slider	85 mph	3-6 inches glove-side	30-36 inches	2:00-3:00	Late, sharp swing-and-miss
Slurve	80 mph	6-10 inches glove-side	40-48 inches	1:30-2:30	Hybrid finisher and chase pitch
Curveball	79 mph	4-7 inches glove-side	50-60 inches	12:00-1:00	Strike-stealer, eye-level change
Sweeper	82 mph	12-18 inches glove-side	32-38 inches	3:00	Horizontal weapon vs same-handed hitters

If you have already read my guides on how to throw a curveball and how to throw a sweeper, the slurve will feel like the middle child of the breaking-ball family. It borrows the depth of a curve and the horizontal action of a slider, without committing fully to either.

Equipment You Need to Get Started

You do not need a lab to learn a slurve, but a few tools will dramatically accelerate the process. I have wasted entire offseasons trying to “feel” my way to a better breaking ball without ever knowing what my spin was actually doing. Once I started measuring, the pitch came together in about three weeks.

A regulation baseball. Leather, not rubber. Rubber practice balls give you false grip feedback.
A radar device. A Pocket Radar Smart Coach or a Stalker Solo II will tell you whether your slurve has enough velocity separation from your fastball. I cover this in detail in my Pocket Radar review.
A spin and shape tracker. Rapsodo Pitching 2.0 or a TrackMan portable is ideal. If you cannot afford one, a smartphone in slow motion at 240 frames per second is a decent substitute.
A pitching net or L-screen. You will throw 60 to 80 quality reps per session. A backstop or a Bownet target with a strike-zone insert keeps it productive.
A baseball with seam markings. Mark the seams with a Sharpie so you can see the spin axis when you record video. This single trick changed my development arc.
Arm-care bands. Jaeger J-Bands or a similar set. Breaking balls put extra stress on the elbow, and you cannot skip recovery work.
A flat ground or a portable mound. Some flat-ground work is fine, but you cannot finalize a slurve without throwing off a real slope. The downhill angle changes how the wrist finishes.

Step-by-Step: How to Throw a Slurve

Here is the exact progression I take pitchers through. Do not skip steps. If you cannot do step three without losing your fastball command, you are not ready for step four. The slurve rewards patience and punishes shortcuts.

Step 1: Set the Grip

Find the horseshoe of the baseball, the spot where the seams form a U shape. Place your middle finger along the right side of the horseshoe (for a right-handed pitcher) so the pad of the finger rests directly on the seam. Your index finger sits next to the middle finger but does not press hard into the ball. Your thumb tucks underneath, slightly off-center toward your palm side, resting on or near the bottom seam.

The grip pressure is what separates a slurve from a curveball. On a true curveball, you grip with the middle finger and lift, almost like throwing a punch with your knuckles. On a slurve, you grip the seam with the middle finger but the pressure is spread more evenly across both fingers, and your wrist is angled slightly to the side rather than completely on top. Think of it as a curveball grip rotated about 15 to 25 degrees toward the slider side of the wrist.

Step 2: Match Your Arm Slot to Your Fastball

The single biggest mistake I see is pitchers dropping their arm slot to “help” the ball break. Hitters read arm slot before they read pitch. If your fastball comes from a high three-quarters slot and your slurve drops to sidearm, every batter at every level will identify it immediately. Your slurve must come from the same slot as your fastball. The break has to come from the wrist and forearm, not from a different release point.

I have my pitchers shadow throw in a mirror for ten minutes a session, alternating fastball and slurve arm actions with no ball. If you cannot tell the difference between the two motions in the mirror, the hitter will not be able to either. This is the foundation of pitch tunneling, and it is non-negotiable.

Step 3: Get the Wrist Set Early

As your arm comes through, your wrist should already be slightly cocked toward your throwing-side ear at the start of acceleration. For a right-handed pitcher, that means the thumb points roughly toward your right shoulder during the early part of the throw. This pre-sets the spin axis at about 1:30 to 2:00 on a clock face. If you wait until the release to twist your wrist, two bad things happen: the pitch flattens because you cannot generate enough spin in that small window, and you put a tremendous amount of unnecessary stress on the medial elbow.

Step 4: Throw Through the Front of the Ball

This is the cue that finally unlocked my slurve. Instead of trying to spin the ball, I imagine throwing my middle finger through the front-outside quarter of the baseball, like I am drawing a diagonal line across its face from upper-right to lower-left. The ball comes out with the seam rotating end-over-end but tilted, which produces the slurve shape. If I try to “throw a curveball,” I roll my wrist too early and the ball pops up. If I try to “throw a slider,” I cut across it and lose all the depth. The slurve lives in the diagonal.

Step 5: Finish Down and Across Your Body

Your follow-through should mirror your fastball but with a slightly more pronounced finish across the front side. The throwing hand should end up near the opposite hip, not slapped down hard at the throwing-side knee. A clean finish protects the elbow and lets the spin do its work. If you yank your slurve, you will see flat shapes and feel a sting on the inside of your forearm. That sting is a warning, not a badge of effort.

Step 6: Target the Glove-Side Corner

The slurve is most lethal on the glove-side edge of the strike zone or just off it. For a right-handed pitcher facing a right-handed hitter, that means starting the ball at the middle of the plate and finishing it on the outside corner or just off the plate away. Aim for the back foot of the same-handed hitter when you want a chase. Aim for the catcher’s outside knee when you want a backdoor strike. I almost never throw a slurve to the arm-side edge, because the shape works against you there.

Drills That Actually Transfer to the Mound

I have tried every breaking-ball drill on YouTube. Most are garbage. Here are the five that actually moved the needle for me and for the pitchers I coach.

1. The Football Spiral Drill

Grab a junior-size football, the kind kids use in pee-wee league. Throw 15 to 20 spirals at about 60 percent effort, focusing on getting a tight, tilted spiral with the nose of the ball pointing down and across. The football exaggerates any wrist deviation and forces you to drive your fingers through the ball at the correct angle. If your football wobbles, your slurve will hang. Spend two minutes on this every bullpen warmup.

2. The Towel Drill With a Tilt

Stand 15 feet from a wall, holding a small hand towel by one end. Mimic your pitching delivery and “throw” the towel so it snaps against the wall. The key is that your wrist should finish at a diagonal tilt, not straight overhand. This drill builds the kinesthetic memory of the wrist position without putting any load on the arm. Do three sets of 10 between bullpens.

3. The Spin-and-Catch Drill

Stand with a partner 15 feet apart. Without any windup, snap-spin slurves to each other using only your wrist and fingers. You are not throwing hard. You are studying the spin axis. Mark a single seam with a Sharpie so you can watch the dot rotate as the ball travels. The dot should appear to circle, not flicker. A flickering dot means your axis is moving and your spin efficiency is poor. Aim for a clean rotating dot at a 1:30 tilt.

4. The Two-Cone Tunnel Drill

Set two cones about halfway between the mound and home plate, roughly six inches apart at chest height, forming a “tunnel window.” Throw alternating fastballs and slurves with the goal of having both pitches pass through the cones. The slurve breaks down and away after the window. The fastball stays true. If a hitter sees both pitches occupy the same window for 30 feet, the slurve is essentially invisible until it is too late.

5. The Hill-and-Flat Comparison

Throw 10 slurves off a flat surface, then 10 off a real mound. Record both on a phone at 240 frames per second. The mound version will reveal whether you are dropping your back side, opening up too early, or leaking your front shoulder. Most pitchers I work with have a slurve that works on flat ground and falls apart on a mound. The hill exposes everything.

Common Mistakes and How to Fix Them

I keep a list of slurve mistakes from every lesson I give. Here are the ones I see in nearly every pitcher, ranked by how often they kill the pitch.

Mistake	What You Will See	Why It Happens	The Fix
Dropping arm slot	Pitch flattens, sweeps with no depth	Pitcher tries to “create” sweep	Mirror work, slot-match drills
Wrist set too late	Flat, hangs in zone, gets crushed	Twisting at release instead of pre-setting	Spin-and-catch drill daily
Squeezing the ball	Loss of velocity, sore forearm	Anxiety or trying to add spin	Hold ball like an egg, pressure with fingertips only
Pulling down through release	Yanked to glove side, no strike	Trying to force the break	Throw through, not down
Spinning the ball softly	Looks like a rainbow, no late break	Lack of intent on release	Throw it at fastball intent, let grip do the rest
Same arm angle as curveball	Pitch becomes a slow curve, not a slurve	Habit from prior pitch	Add wrist tilt at set position, not at release
Tipping the pitch	Hitters sit on it	Glove flares, grip visible	Set grip in glove, deeper glove position
Throwing only to glove side	Becomes predictable	Comfort zone trap	Mix in backdoor slurves to opposite-handed hitters
Overuse	Elbow soreness, declining velocity	Loving the pitch too much	Cap at 25-30 percent of total pitches
No fastball setup	Slurve hit hard	Pitch in a vacuum	Build sequences, see pitch sequencing guide

Advanced Tips for Pitchers Who Already Throw a Slurve

If you can already throw a slurve for a strike, the next step is making it a weapon. These are the adjustments I started making once I had the base shape locked in.

Develop Two Slurve Shapes

The best slurve pitchers I have studied throw two versions: a slower, bigger one for early counts to steal strikes, and a harder, tighter one for two-strike counts to bury below the zone. The grip is the same. The difference is intent and finish. The early-count version is thrown at 85 percent effort with a slightly longer finish. The two-strike version is thrown at 100 percent with a sharp, abbreviated finish. Hitters who time the first one cannot adjust to the second.

Use the Backdoor and Front Door

A backdoor slurve starts off the plate to the opposite-handed hitter and breaks back to nip the outside corner. A front-door slurve starts at the hitter’s hip and breaks back over the inside corner for a called strike. Both are top-of-the-zone pitches and both require absolute conviction. The slightest hesitation produces a hanger.

Pair It With a Fastball Up and In

If your fastball lives up and in to same-handed hitters, your slurve down and away becomes nearly unhittable. The eye level changes, the planes diverge, and the hitter has to make a decision before recognizing the pitch. This is straight out of the pitch sequencing playbook and it is the single biggest sequencing concept young pitchers underuse.

Measure Spin Efficiency, Not Just Spin Rate

Spin rate is overrated. Spin efficiency, also called active spin, is what actually moves the ball. A slurve at 2,600 rpm with 85 percent active spin will out-break a slurve at 2,900 rpm with 60 percent active spin every single time. Track active spin on a Rapsodo or TrackMan and chase efficiency, not raw revolutions.

Vary Your Tilt

Once you own a 1:30 tilt slurve, experiment with a 2:30 tilt version that runs more horizontally. Now you essentially have a slurve and a hybrid slurve-sweeper, both off the same arm action. Hitters cannot sit on a single shape, and your put-away rate will climb.

Sequencing the Slurve in Real Game Situations

A slurve in a vacuum is just a curve with personality. A slurve in the right sequence is a wipeout pitch. Here are the sequences I trust most.

0-0 to a same-handed hitter: Fastball arm-side corner, slurve back-foot. 0-0 hitters do not swing at slurves. Free strike or weak contact.
1-1 to a same-handed hitter: Fastball up and in, then slurve away. Eye-level shift is the kill move.
0-2 to anyone: Bury the slurve in the dirt off the plate. Do not throw it for a strike. You earned the chase, take it.
2-2 to an opposite-handed hitter: Backdoor slurve to the outside corner. Hitter sees it begin off the plate and gives up before it breaks back.
3-2 to a same-handed hitter: Fastball middle, slurve glove-side corner. The hitter has to honor both, and the slurve in the strike zone late in the count is a confidence pitch.

Arm Care and Workload Management

I will not dance around this. Breaking balls put extra torque on the elbow, and the slurve is no exception. Multiple studies on youth and high school pitchers have linked early and heavy curveball use to elevated UCL injury rates. The data is mixed on whether breaking balls are uniquely dangerous compared to high-velocity fastballs, but no one disputes that volume matters and that bad mechanics accelerate damage.

Age limits. I do not teach a true slurve to pitchers younger than 13 or 14. Before that, focus on fastball command and a basic changeup.
Pitch caps. Slurves should not exceed 25 to 30 percent of your total pitches in a game. If you throw 80 pitches, that is 20 to 24 slurves max.
Recovery work. Do not skip arm care. My arm care routine guide covers band work, sleeper stretches, and forearm massage. Twenty minutes a day, every throwing day.
Listen to forearm pain. Soreness in the medial forearm or elbow after slurves is a red flag. Back off velocity, shorten the bullpen, and see an arm-care specialist if it persists for more than 48 hours.
Long toss matters. Build arm strength with progressive long toss between starts. See my long toss guide for a program that works.

Building a Bullpen Routine Around the Slurve

Here is a sample 40-pitch bullpen that I use to integrate slurve work without sacrificing fastball command.

Pitches 1-8: Fastballs to all four corners, building from 60 percent to 90 percent effort.
Pitches 9-14: Slurves at 70 percent, focused on spin and shape, not location.
Pitches 15-22: Fastball-slurve combinations, tunneling through the imaginary cone window.
Pitches 23-30: Changeups and any third pitch you throw, restoring rhythm.
Pitches 31-36: Slurves at 100 percent, hitting both glove-side corner and below the zone.
Pitches 37-40: Simulated at-bats: 0-0, 1-1, 2-2, 0-2 sequences against an imaginary hitter.

Forty pitches is plenty for development. Throwing 70 pitches in a bullpen because you cannot find the shape is counterproductive. If you cannot snap a slurve by pitch 30, the issue is not volume, it is feel. Stop, walk five steps, breathe, and try again with less effort.

How to Practice the Slurve in Cold Weather

If you live in the northern half of the country, March bullpens are going to be cold. Cold weather kills feel, and breaking balls are 90 percent feel. A few adjustments I make every spring:

Longer warmup. I add ten extra minutes of band work and light tossing before I even consider snapping a breaking ball.
Tackier grip aid. A small amount of pine tar substitute or grip rosin can make a huge difference when your hands are numb. Stay within whatever rules your league enforces.
Heat pad in the dugout. Between innings, I sit on a chemical hand warmer with my throwing hand wrapped. Sounds silly. Works.
Reduce expectations on shape. Cold air affects ball flight. A slurve that has 8 inches of break in July might have 5 in March. Trust the process, not the perfect shape.

FAQ: Questions I Get About the Slurve

Is the slurve safe for youth pitchers?

I would not teach a true slurve before age 13 or 14, and only then if the pitcher has clean mechanics, can locate a fastball to both sides, and has a usable changeup. The slurve requires a wrist action that, done poorly, puts unnecessary stress on the medial elbow. Build the foundation first. The pitch will still be there in a year.

What is the difference between a slurve and a slider?

A slider has a tight, late, mostly horizontal break and lives around 85 mph in the majors. A slurve has more depth, sweeps a bit longer, and sits a few miles per hour slower. The grip is similar but the wrist tilt at release is more pronounced on a slurve.

How do I know if I am throwing a slurve or a slow curve?

Check velocity separation from your fastball. A slow curve is typically 14 to 18 mph slower than your fastball. A slurve should be 8 to 12 mph slower. If your “slurve” is 17 mph off the fastball, you are throwing a curve. Adjust by tightening the wrist tilt and committing to more intent at release.

Can left-handed pitchers throw a slurve?

Absolutely. Reverse everything in this guide. A left-handed slurve breaks down and to the left from the catcher’s view, with a 10:30 to 11:30 spin axis. Lefty slurves are especially nasty against right-handed hitters because they replicate the back-foot path that right-handers see less often.

What grip pressure should I use?

Hold the ball like you would hold a fragile egg. Pressure should come from the fingertips on the seams, not from a clenched palm. Death grip kills velocity and produces tendinitis. I tell my pitchers to imagine they could squeeze a sponge inside the ball without crushing it.

How long does it take to learn a slurve?

For pitchers who already throw a curveball or slider, two to four weeks of focused bullpens. For pitchers starting from scratch, expect two to three months before it is game-ready. Do not rush it. A bad slurve thrown in games will get hit hard and shake your confidence.

Should the slurve replace my curveball?

Usually no. Most arsenals benefit from having distinct shapes. If your curveball is a true 12-6 with big depth, keep it. Add the slurve as a second breaking ball to attack same-handed hitters. If your curveball is mediocre, then yes, transitioning to a slurve might make sense. Ask a pitching coach with eyes on your shapes.

Will the slurve hurt my elbow?

Not if you throw it with proper mechanics and reasonable volume. The slurve does require wrist action, and wrist action transmits force through the forearm and elbow. Keep your arm slot matched to your fastball, do not over-twist at release, cap your volume, and do your arm care work. The pitchers I see get hurt are the ones who throw 50 slurves a day with bad mechanics.

How do I read spin axis on a tracker?

Most trackers display spin axis like a clock face from the pitcher’s view. A 12:00 axis is pure backspin (a four-seamer). A 6:00 axis is pure topspin (a 12-6 curveball). A slurve lives at 1:00 to 2:30 for a right-handed pitcher. The closer to 1:00, the more curveball-like. The closer to 3:00, the more slider-like.

What if I cannot generate enough spin?

Spin is a function of finger strength, grip stability, and release speed. Train all three. Forearm and finger strength work, especially with weighted balls and rice bucket exercises, will add spin over time. Be patient. A 12 percent jump in spin rate in a single offseason is realistic and meaningful.

Where the Slurve Fits in a Modern Arsenal

The modern MLB pitcher carries an average of about 4.5 distinct pitches, and breaking ball variety is the single biggest separator between mid-rotation arms and aces. A typical big-league arsenal in 2026 might look like: four-seamer, sinker, slider, changeup, and either a slurve or a sweeper. The reason the slurve has come back is that hitters have become very good at identifying pure shapes, and a hybrid pitch buys an extra few milliseconds of indecision. That is the entire game above 90 mph.

If you want to see how the slurve fits into broader pitch design, my guides on the complete pitching grips library and how to pitch from the stretch are the next places to go. The slurve is just one piece of a much larger puzzle.

Final Thoughts

The slurve is not a magic pitch, and it is not for everyone. It rewards pitchers who are willing to be patient, measure honestly, and treat their arm with respect. If you treat it like a shortcut to strikeouts, it will betray you. If you treat it as a craft, it will reward you for years.

Take it slow. Start with the grip and the football drill. Move to spin-and-catch. Then to flat ground. Then to the mound. Track your shapes, track your velocity, and track your effort level. Throw 60 to 80 quality reps per session, not 200 mindless ones. And remember: a good fastball makes a great slurve. A bad fastball makes a great slurve irrelevant. Build the base first.

Now go throw one. And then go throw a thousand more.
