Fielding Percentage — Definition, Formula & Youth Context
Fielding Percentage measures how often a player successfully completes a defensive play. Formula: (Putouts + Assists) ÷ (Putouts + Assists + Errors). A .950 fielding percentage means the player successfully makes the play 95% of the time. It's the most common defensive stat in baseball, but at the youth level, it tells you less than you'd think — because errors are frequent, scoring is inconsistent, and the stat doesn't account for range.
The Formula
Fielding Percentage = (PO + A) ÷ (PO + A + E)
Where:
- PO = Putouts (the fielder recorded the out)
- A = Assists (the fielder threw to another fielder who recorded the out)
- E = Errors (the fielder made a mistake that allowed a runner to reach or advance)
Example: A shortstop with 25 putouts, 40 assists, and 7 errors:
Fielding % = (25 + 40) ÷ (25 + 40 + 7) = 65 ÷ 72 = .903
Fielding Percentage by Position (12U)
Position matters enormously. An outfielder faces routine fly balls. A shortstop faces hard-hit grounders, bang-bang throws, and relay plays. Same team, very different fielding percentages.
| Position | Average (12U Competitive) |
|---|---|
| Pitcher | .900-.950 |
| Catcher | .880-.930 |
| First Base | .940-.970 |
| Second Base | .900-.940 |
| Shortstop | .880-.930 |
| Third Base | .880-.930 |
| Outfield | .920-.960 |
Shortstops and catchers will always have lower fielding percentages than first basemen and outfielders — they handle more difficult plays.
What Fielding Percentage Misses
Range. A player who gets to 50 ground balls and makes errors on 5 has a .900 fielding percentage. A player who only gets to 30 ground balls (because they can't move laterally) and errors on 1 has a .967. The second player looks better statistically but is objectively worse defensively — they just never got to the hard plays.
Arm strength. Fielding percentage doesn't measure how hard or accurately a player throws. A third baseman with a weak arm might field the ball cleanly but throw it in the dirt at first. Depending on the scorer, that might be an error on the third baseman or first baseman.
Positioning and instincts. The best youth fielders read the bat, anticipate the ball, and position themselves correctly before the pitch. None of that shows up in fielding percentage.
When Fielding Percentage Is Useful
Despite its limitations, fielding percentage has value when used correctly:
Tracking error trends. If a player's fielding percentage drops over a stretch of games, something changed — fatigue, focus, mechanics. It's worth investigating.
Comparing the same player over time. A shortstop whose fielding percentage improves from .850 to .920 across a season is making real defensive progress.
Identifying position fit. A player with a .970 fielding percentage at first base and .800 at shortstop probably should stay at first base for game situations, while developing at shortstop during practices.
Frequently Asked Questions
What's a good fielding percentage for a 10U player?
Lower than you'd expect. A .850 fielding percentage for a 10U infielder is normal. Youth baseball involves a lot of errors — the balls are hit harder relative to fielding ability, and throwing accuracy is still developing. Age benchmarks →
Does Rizzler track fielding percentage?
Yes. When you score games in Rizzler, putouts, assists, and errors are recorded. Fielding percentage calculates automatically per player and per position.
Should I bench a player with a low fielding percentage?
No. Especially not at the youth level, where errors are part of learning. Use AI Fielding Positions to put players where they can succeed while also giving development opportunities at challenging positions during lower-stakes innings.
