Two-Handed Spare Shooting: How Thumbless Bowlers Cover the Corners

Your strike ball is not the problem. Watch a good two-hander for three games and you’ll see plenty of pocket. Then you’ll see the 10 pin sitting there in the sixth, and again in the ninth, and the 220 turns into a 178.

Here’s the part nobody tells you when you start bowling two-handed: the spare system almost everybody teaches was built for a bowler who stands near the middle of the approach. You don’t. You start deep, you rev it hard, and when you try to run the standard moves, you literally run out of approach.

That’s a geometry problem, not a talent problem. Fix the geometry and your spare percentage jumps without touching your release.

Why the 3-6-9 system breaks for two-handed bowlers

The 3-6-9 system works off your strike shot. You keep your strike target, then move your feet 3 boards for one pin, 6 for another, 9 for the next. For a right-hander shooting the 10 pin, the classic version asks for a 12-board move left.

Now do that math as a two-hander.

Say you play the fresh house shot standing around board 30 with your slide foot. Twelve boards left puts you on board 42. The approach only has 39 boards. You are standing in the ball return.

Even if you play a little more direct and start on 25, a 12-board move drops you on 37 with your swing crowding the edge and your walk squeezed into nothing. You’ll drift right to make room, and drifting right on a 10-pin shot is exactly how you pull it through the nose.

This is not a hypothetical. Nick Pollak, a two-handed bowler and USBC Bronze coach, put it plainly in his breakdown of two-handed spare shooting: two-handers are already so deep on the lane that moving 12 boards left is not possible, so that conversion system will rarely work.

The fix is not to squeeze the old system into a smaller space. It’s to stop starting from your strike shot at all.

Start from a fixed corner-pin position

The better approach for a two-hander is the same one most pros use. Pick a dedicated spot for each corner pin, throw the ball straight at the pin from there, and build every other single-pin move off that corner spot.

You are not adjusting for lane conditions anymore. You’re taking ball reaction out of the equation entirely.

USBC Gold coach Michelle Mullen laid out the reference angles in a USBC spare shooting clinic, and they’re the right starting point even if your finish position ends up different.

The 10 pin, right-handed

Mullen’s reference for a one-hander is roughly board 35 with the slide foot, targeting between the third and fourth arrows. Right-handers count arrows from the right, so that’s the 20 to 25 board area.

As a two-hander you’ll usually need more angle than that. Pollak stands on board 39 and sends the ball across the third and fourth arrows. That’s the outside edge of the approach, and there’s a reason: your ball still wants to turn left, so you need a steeper cross-lane path to beat it.

Start at 35. If the ball is finishing left of the 10 pin, walk yourself out toward 37, 38, 39 until it’s dead on.

Open your stance. Point your shoulders, hips and feet at the pin before you ever start walking. Then walk straight and finish on the same board you started on.

The 7 pin, right-handed

This is the one that feels bizarre. Mullen’s reference is around board 15 with your shoulders closed, still targeting between the third and fourth arrows.

Closed shoulders means you turn your upper body to face the 7 pin, which for a right-hander feels like you’re aiming at the wall. You’re not. Almost everybody who tries it thinks they’re facing the pin and isn’t, so film it once from behind and check.

For the 7 pin, you’ll walk slightly toward your target instead of straight, because your swing is on the right side of your body and your shoulders are closed. The one thing you never do is drift toward your armswing.

If you bowl left-handed

Mirror everything and count your boards from the left edge. The 7 pin becomes your open-stance shot from way outside, around board 35 counting from the left. The 10 pin becomes your closed-shoulder cross-lane shot from around board 15 counting from the left.

The pin groupings don’t change. The 4 pin and then the 2 or 8 come off your 7-pin spot. The 6 pin and then the 3 or 9 come off your 10-pin spot. And in both cases, and for both hands, the 3-board and 6-board moves go toward the middle of the approach.

Reverse 3-6-9: move off the corner pin, not the headpin

Once you own your two corner spots, every other single pin is a small move off the nearest corner. This is the reverse 3-6-9, and it’s the piece that makes the whole thing work for a two-hander.

You keep the same target between the third and fourth arrows. Only your feet move.

Right-handed two-handers:

There’s no 9-board move in either direction. Nine boards puts you back at the headpin, and that’s just a strike shot.

Note what’s missing from that chart: any move based on where the headpin is. Everything is measured from the corner. That’s the whole trick, and it’s why this survives a burned-up back end in the ninth frame when your strike line has moved five boards left.

If you want the one-handed version of these systems side by side, we broke it down in 3-6-9 vs 2-4-6.

The release change that makes a straight ball possible without a thumb

Board numbers are useless if the ball still hooks four boards. This is where thumbless bowlers have to do work that one-handers skip, because you can’t just stick your thumb in and kill the revs.

Four things, in order of how much they matter.

1. Get your hand behind the ball. Your strike release has your hand under and around the side of the ball, imparting side rotation. For spares you want your fingers pointed straight up the lane at release, rotation close to 12 o’clock. Same swing, different hand position.

2. Relax the wrist. A firm or cupped wrist is what stores the revs. Let it go soft and neutral. You’ll feel the ball come off flatter, and that’s the point.

3. Take the second hand off earlier. You do not have to abandon two-handed form to shoot spares, but the later your off hand stays on the ball, the more it drives rotation. Releasing the support hand a beat earlier through the bottom of the swing bleeds revs without wrecking your balance.

4. Add speed, not muscle. More ball speed means less time for friction to work. Hold the ball a little lower in your stance and walk a touch closer to the line. Don’t try to throw it harder, because that just adds tilt and hook.

Some two-handers go further and shoot corner pins one-handed with the same two-finger grip. It’s legal, it’s simple, and it flattens the ball out more than anything on this list. If your 10 pin is genuinely costing you 20 pins a set, it’s worth ten frames of practice to find out whether it suits you.

Your spare ball, and the USBC rule that catches two-handers

You want plastic. Polyester, low differential, no surface. It’s the cheapest 10 pins you will ever buy and you’ll throw it more than any ball in the bag except your benchmark.

Here’s where two-handers get themselves in trouble.

USBC eliminated balance holes effective August 1, 2020. Since then, every gripping hole in your ball must be used on every delivery. And under the USBC gripping-hole rule, any thumb hole you do not actually use for gripping during the delivery is classified as a balance hole.

Put those together and you get a rule a lot of two-handers break by accident: a plastic spare ball drilled with a thumb hole you never put your thumb into is not legal in USBC certified competition. It’s not two holes and a spare, it’s a two-finger grip plus an illegal balance hole.

So you have two clean options.

Option A, the common one. Drill the plastic ball two-finger, no thumb, same as your strike balls. Nothing to think about, legal everywhere, and it matches the grip you already trust.

Option B, thumb in for spares only. You can use your thumb on spare shots if you want, but the ball has to meet static balance specs measured both ways, from the middle of the grip with the thumb in and from the center of the bridge with the thumb out. That means no extra holes at all. Tell your driller exactly what you’re doing before they lay it out, not after.

One more rule worth knowing if you switch things up mid-game. USBC Playing Rule 4f says that when you use a two-handed technique, the gripping holes have to be used by the same hand. Your off hand supports the ball. It does not go in it.

If your plastic ball is older than 2020 and has a plug or an extra hole in it, get it checked before the next sanctioned event. Your pro shop can sort it in an afternoon, and our pro shop page is a decent place to start if you need gear.

Walk your line, because drift is what actually misses

You can have perfect board numbers and still miss the 10 pin right, every time, for a whole season.

The cause is almost always drift. You set up on 35, you walk toward the middle out of habit, and you finish on 30. Now your ball is starting five boards inside where you planned, and the angle you carefully built is gone.

Two checks that cost you nothing:

• Put down a piece of tape at your start board and look at your slide foot after the shot. If you started on 35 and finished on 30, that’s your miss. Not your release.
• Never drift toward your armswing. For a right-hander that means never drifting right on a 10-pin shot. Your swing needs room, and drifting into it forces you to pull the ball across your body.

Two-handers drift more than one-handers because the second hand pulls your torso around. It’s worth being obsessive about this one.

Multi-pin spares and washouts

Split the difference between the two single-pin positions.

For a 4-7, the 7 pin is its own shot and the 4 pin is three boards left of it. So you stand roughly a board and a half left of your 7-pin spot. For a 2-8, the 2 pin is the key pin, so you use your 2-pin move, which is six boards left of the 7-pin position.

For a 2-4-5, the 2 pin is still the key pin. Same move.

The general rule: find the key pin, use its number, adjust a board if the ball tells you to. You need to be more accurate on multi-pin leaves, but you’re still taking lane transition out of play, which is the whole reason you’re doing this.

Baby splits like the 3-10 and 2-7 are their own animal and depend on hitting a specific side of the front pin. We covered those separately in how to pick up baby splits.

Three drills that fix a two-handed spare game

1. Ten in a row. Set the machine to full rack, ignore the rack, and throw ten straight balls at the 10 pin from your spare spot with your plastic ball. Not five, not “a couple during practice.” Ten. Count how many you’d have converted. That number is your real spare percentage, and it’s usually worse than you think.

2. Tape and film. Tape your start board. Film one shot from directly behind. Check three things: did your shoulders actually face the pin, did you finish on the board you started on, and did the ball cross between the third and fourth arrows. Fix whichever one is off before you touch anything else.

3. Corner pin ladder. Shoot the 10, then the 6, then the 3, using only the 3-board moves. Then do the same on the left with the 7, 4 and 2. This builds the muscle memory that your feet do the work and your target never moves.

Do these for three practice sessions and you’ll stop thinking about spares in league. That’s the goal. The bowler who has to solve a 10 pin from scratch under pressure is the bowler who misses it.

Frequently asked questions

Can two-handed bowlers shoot spares one-handed?

Yes. Plenty do, especially on corner pins. You keep the same two-finger grip and simply take the support hand off. It flattens the ball out and it’s fully legal, since your gripping holes are still all used by the same hand. It takes practice to control speed and accuracy with one hand, so build it in practice before you trust it in the tenth frame.

What board should a two-handed bowler stand on for the 10 pin?

Start around board 35 with your slide foot, targeting between the third and fourth arrows, and adjust outward from there. Many two-handers end up between 37 and 39 because the extra revs need a steeper cross-lane angle. Your rev rate and speed decide the final number, so find it in practice, not in league.

Do two-handed bowlers need a plastic spare ball?

You want one. A plastic ball is the simplest way to take ball reaction and lane transition out of your spare game, and for a two-hander who generates a lot of side rotation, it’s the difference between a straight ball and a four-board hook at the corner. Drill it two-finger, no thumb hole.

Why do two-handed bowlers miss the 10 pin so often?

Three reasons stack up. The standard 3-6-9 move doesn’t physically fit on the approach for a bowler who starts deep. High rev rates make the ball hook back even on plastic. And two-handers drift more, because the off hand pulls the torso around through the approach. Fix the starting position first, the release second, and the drift third.

Is the reverse 3-6-9 system better than the regular 3-6-9?

For two-handers, yes, because it fits on the approach and it doesn’t depend on your strike line, which moves all night. For one-handers it’s a matter of preference, though most pros now go straight at their spares off fixed corner positions rather than adjusting off a strike shot.

Can I use my strike ball for spares as a two-hander?

You can on the 1, 5, 8 and 9, where you’re basically throwing a strike shot. On corner pins it’s a bad trade. Your strike ball reads friction that’s changing every game, so you’re solving a new problem every time you face a 10 pin. Plastic makes it the same shot in the first frame and the tenth.

10th Frame Final Thoughts

The two-handed strike ball gets all the attention. The two-handed spare game is where the average actually lives.

Nothing here asks you to change your delivery. You’re picking two fixed spots, moving your feet in 3s and 6s, flattening your hand out, and throwing plastic. That’s it.

Get your equipment checked while you’re at it. A plastic ball with an unused thumb hole in it has been illegal since 2020, and it would be a rough way to lose an award score.

Ten balls at the 10 pin next practice. Count them honestly. Then go fix the number.
