Youth Baseball Stats Cheat Sheet: Formulas Every Coach Should Know
The stats that matter most for youth baseball and softball, what each one measures, the formula, and the coaching decision it is good for. Batting average and ERA are not on the list on purpose: at the youth level both are swamped by errors and small samples, and the stats below tell you more with the same box score.
| Stat | What it measures | Formula | Use it for |
|---|---|---|---|
| OBP | How often a hitter reaches base | (H + BB + HBP) ÷ (AB + BB + HBP + SF) | Leadoff and top-of-order hitters |
| SLG | Power: total bases per at-bat | Total bases ÷ AB | Finding run producers |
| OPS | On-base ability plus power | OBP + SLG | Best single hitting stat |
| BB/PA | Plate discipline | BB ÷ PA | Rewarding a good eye |
| BABIP | Results on balls in play (luck check) | (H − HR) ÷ (AB − K − HR + SF) | Separating luck from skill |
| LD% / GB% / FB% | Type of contact | Type ÷ balls in play | Coaching swing path |
| K/BB | Pitcher command | K ÷ BB | Finding strike-throwers (2+ is strong for youth) |
| WHIP | Baserunners allowed per inning | (BB + H) ÷ IP | Who keeps innings clean |
| FIP | Pitching independent of defense | (13×HR + 3×(BB + HBP) − 2×K) ÷ IP + constant | Picking your true ace |
| ERA | Earned runs per regulation game | ER × innings per game ÷ IP | Pitching + defense together |
| FPCT | Errors on chances handled | (PO + A) ÷ (PO + A + E) | Comparing within one position only |
| CS% | Runners thrown out stealing | CS ÷ SB attempts | Catchers — with context |
