Every split feels like a punishment. Most of them are. But the baby split is the one leave you have no business missing, and if you are giving it away on league night, it is quietly costing you games.
If you want a second angle, this BowlVersity guide on converting split leaves lays out the foot and target moves too.
Here is the reality. A 190 bowler who chops one makeable split a set is bleeding 15 to 20 pins a night for no reason. That is the difference between a 190 book average and a 200. You do not need a new ball to fix it. You need a plan for the split you actually leave.
So let’s break down the baby splits, the 2-7, the 3-10, and their nastier three-pin cousins, and give you a repeatable way to close them instead of hoping.
What a baby split actually is
A split is any leave where the headpin is down and you are left with two or more pins that have a gap between them. A baby split is the friendly version. The pins sit close enough together that a ball, or one pin sliding into the other, can cover both.
The classic baby splits are the 2-7 and the 3-10. They are mirror images of each other. A right-handed bowler leaves the 3-10, out on the right. A lefty leaves the 2-7, out on the left. Same shape, opposite side.
They happen the same way too. Your ball comes in a touch high or light, clips the headpin, and chops the 2 pin off the front (leaving the 7 behind it) or the 3 pin off the front (leaving the 10 behind it). The pin you chopped is gone. The corner pin behind it is stranded.
The good news is right there in the name. These are the makeable ones. Intermediate league bowlers convert baby splits well over half the time once they stop guessing. The distance between the two pins is small enough that you have real margin to work with.
The one idea behind every baby split
Forget the gap. That empty space between the two pins is what your brain fixates on, and it is exactly the wrong thing to look at.
There are only two ways to make a baby split, and both start with the front pin:
- Graze both pins with the ball. You thread the edge of the ball across both, taking the front pin and carrying through to the corner.
- Carom the front pin into the back one. You hit the front pin thin on its outside edge so it slides sideways across the deck and knocks the corner pin down for you.
On the tighter baby splits, that carom is doing most of the work. You are not trying to squeeze the ball into a gap. You are hitting the front pin on the correct side so it does the traveling.
That means your target is a pin, not a space. Aim at the front pin, on the side that sends it toward the corner, and let physics finish the job.
How to pick up the 3-10 (right-handers)
The 3-10 is the split most righties leave, so this is the one to own first.
The goal is to hit the 3 pin on its right side. When you catch the 3 thin on the right, two things can happen and both are good. The ball drives forward toward the 10, or the 3 pin caroms right into the 10. Either way, the corner falls.
Here is the mental trick that makes it click. Shoot the 3-10 as if the 6 pin were still standing between them. Aim for the spot where the 6 would be, right between the two pins. Coaches teach it as treating the leave like a 3-6-10. That reframe stops your eyes from drifting into the empty gap and gets them onto a real line.
For alignment, work off your 10-pin or washout line. A common move is to set up as if you are covering the 3 and 6, then shift about 5 boards to line the ball up through that phantom 6 spot. Use the same down-lane target you trust for the right-side pins, just angled to catch the 3 on the outside.
The one rule you cannot break: hit the 3 thin, not full. Catch the 3 flush in the middle and you drive it straight back, the ball deflects left, and the 10 stands there laughing. Thin on the right side is the whole shot.
How to pick up the 2-7 (lefties, and righties who pull it)
The 2-7 is the mirror. Lefties leave it as their standard baby split, and right-handers see it when they pull the ball and come in too high on the nose.
Everything flips. You want to hit the 2 pin on its left side so it slides across into the 7, or so the ball carries through to the corner. Aim through the spot where the 4 pin would be, right between the 2 and the 7, and treat it like you are shooting a 2-4-7.
For a lefty, this works off your 7-pin line, moved to catch the 2 thin on the outside. For a righty stuck with a 2-7, line up like you are shooting the 4 pin and clip the 2 slightly so it deflects across. Same board logic as the 3-10, just pointed the other direction.
The 2-8-10 and 3-7-9: the tougher cousins
Modern reactive balls hook hard, and that extra angle leaves more three-pin splits like the 2-8-10 for righties and the 3-7-9 for lefties. These are still convertible, but be honest with yourself. They are harder than the two-pin baby splits, and they demand a cleaner hit.
Take the 2-8-10 for a righty. The move is to clip the 2 pin thin on its right side so it slides back into the 8, while the ball keeps driving down and out toward the 10. You are asking the front pin to take the middle pin and the ball to finish the corner. It is a precise ask. Miss thin and you leave the 8 and 10. Miss full and you drive the 2 straight back and leave the 10.
The 3-7-9 is the lefty mirror. Clip the 3 thin on the left into the 9, ball carries to the 7. Same principle, opposite side.
Play these as bonus conversions. When you make one, it is a swing in your favor. When you catch the front pin clean and still leave a corner, tip your cap and move on. You attacked it the right way.
Speed and surface: throw it straight and firm
This is where most baby splits get lost, and it has nothing to do with aim.
Throw it straight. On a normal spare you might get help from a neighboring pin. On a baby split there is no helper pin sitting where you need it, so any hook that grabs late will pull the ball off the line and hand you the miss. Take the hook out. Flatten your hand or, better, use a plastic spare ball that rolls end over end.
Throw it firm. A soft, lobbed ball deflects more on contact, and deflection is your enemy when you need the ball to carry through to a corner pin. Send it with the same speed you throw your strike ball, or a touch more. Firm and straight beats slow and hooking every time on these leaves.
This is the whole reason plastic spare balls exist. If you own drilled reactive equipment and you are still throwing your strong ball at the 3-10, you are fighting your own hook for no reason.
Mistakes that turn a makeable split into an open
First, hitting the front pin too full. This is the number one killer. Catch the 3 or 2 flush and you send it straight back instead of across. Thin on the outside edge is the target, every time.
Second, aiming at the gap. Your eyes want to split the difference and aim at the empty space. Do that and you glance both pins or thread through cleanly and hit neither. Aim at the front pin.
Third, hooking it. A reactive ball that grabs pulls you off your line right when precision matters most. Straight and firm, or plastic.
Fourth, babying the speed. Nerves make people lob the split shot soft. Soft equals deflection equals the corner pin standing. Commit and send it.
Fifth, no plan. If you walk up to a 3-10 and just aim in the general direction and hope, you will make it sometimes and never know why you missed. Pick your line, pick the side of the pin, and repeat it.
Frequently asked questions
What is a baby split in bowling?
A baby split is a split where the two standing pins are close together, making it one of the easier splits to convert. The classic examples are the 2-7 and the 3-10, which are mirror images of each other. It gets the “baby” name because the pins sit near enough that the ball, or one pin sliding into the other, can cover both.
Is the 3-10 split easy to pick up?
It is one of the more makeable splits, yes. Experienced league bowlers convert it well over half the time. The key is hitting the 3 pin thin on its right side so it slides into the 10 or the ball drives through, rather than catching it full and deflecting away from the corner.
Which pin do you hit on the 3-10 split?
You aim at the 3 pin, the front one, and try to catch it thin on its right edge. A helpful trick is to aim through the spot where the 6 pin would be if it were standing, treating the leave like a 3-6-10. That keeps your eyes on a real line instead of the empty gap.
Do you hook the ball on a baby split?
No. Throw it straight and firm. There is no neighboring pin to help you carry, so any hook that grabs late pulls the ball off your line and causes a miss. Flatten your release or use a plastic spare ball that rolls straight.
What is the difference between the 2-7 and the 3-10 split?
They are mirror images. Right-handed bowlers typically leave the 3-10 on the right side of the deck, and left-handed bowlers leave the 2-7 on the left. The conversion is the same logic flipped: hit the front pin thin on its outside edge and slide it into the corner.
Should you use a plastic ball for splits?
If you have one, use it. A plastic spare ball rolls straight and takes hook out of the shot, which is exactly what a baby split needs. Both conversions depend on a clean, straight path to the front pin, and a strong reactive ball fights that with late hook.
10th Frame Final Thoughts
The baby split is not a lost cause. It is a spare with an attitude, and it falls to a bowler with a plan.
Stop looking at the gap. Look at the front pin. Hit it thin on the outside, throw it straight and firm, and let the carom finish the corner. Own the 3-10 first if you are a righty, the 2-7 if you are a lefty, then add the three-pin cousins as bonus makes.
Groove it in practice, not in the 10th frame. Throw a rack of them on a quiet set until the line is automatic. Then when you leave one with the game on the line, you already know the shot. Send it and go down swinging.
