Short answer: Track average, first-ball average, strike percentage, spare conversion, single-pin spare conversion, open frames per game and splits for every athlete, plus pins per Baker frame by position if your matches include Baker. Average tells you where a bowler is. The other numbers tell you what to practice.
Most high school programs track one number: average. It's the number on the lineup card and the one parents ask about. It's also the least useful number for coaching, because it tells you where a bowler is and nothing about why. Two bowlers with the same 165 average can need completely different practice plans.
The stats worth tracking, and what each one tells you
| Stat | How to figure it | What it tells you |
|---|---|---|
| Average | Total pins divided by games | Where the bowler is. Use it for seeding, not for coaching. |
| First-ball average | Pins knocked down on first balls divided by frames | How well they're hitting the pocket. A low number usually points to a targeting or speed problem, not a spare problem. |
| Strike % | Strikes divided by frames | Pocket hits that carry. Matters most for your Baker anchor and position 4. |
| Spare conversion | Spares made divided by spare chances | The fastest way to raise a team score. Every missed spare costs at least 10 pins. |
| Single-pin spare % | Single-pin spares made divided by single-pin chances | Should be close to 100 percent. When it isn't, it's usually a spare system or a spare ball problem, and it's very coachable. |
| Open frames per game | Frames with no strike or spare, per game | The quickest read on consistency. |
| Splits | Count of split leaves | Separates bad luck from bad pocket hits. Lots of splits often means the ball is coming in too light or too high. |
| Pins per Baker frame, by position | Pins produced in that slot divided by frames bowled there | The number to build a Baker lineup from. |
Which number to work on first
- Single-pin spares. If a bowler misses single pins, fix that before anything else. It's the cheapest pins on the lanes.
- Spare conversion overall. Most high school bowlers gain more from spares than from strikes.
- First-ball average. Once spares are solid, work on hitting the pocket more often.
- Strike %. Comes last, and usually follows on its own once the first ball improves.

Tracking it on paper
You can track all of this with a pencil. Mark each frame as strike, spare, open or split, and circle single-pin leaves. Add it up after each match. Our free printable season stat sheet has a row per athlete, a weekly column for each stat, and a Baker section by position. It takes a few minutes per match once you get the hang of it.
Tracking it in LaneLogic
If you score matches in LaneLogic, every athlete gets the same full stats page automatically: average, first-ball average, strike and spare percentages, single-pin spares, open frames, splits, and a pin-by-pin view of their leaves. Baker frames are credited to the bowler who threw them and the position they threw from. Team programs let you keep separate teams (varsity, JV, boys, girls) in one place, and assistant coaches join free with an invite code. You can export everything as CSV or PDF for your athletic director or end-of-season awards.

Frequently asked questions
What is the most important stat for a high school bowler?
Spare conversion, especially single-pin spares. Every missed spare costs at least 10 pins, and spares are the most coachable part of the game.
What is first-ball average in bowling?
The average number of pins knocked down on the first ball of each frame. It shows how well a bowler is hitting the pocket.
How do you calculate spare conversion percentage?
Divide spares made by spare chances (frames that weren't strikes) and multiply by 100.
Do high school bowling coaches need to track Baker stats separately?
If your matches include Baker games, yes. Track pins per Baker frame for each bowler in each position, because that is what a Baker lineup should be built from.
