Baseball Stats, Explained for Parents: AVG, OBP, OPS and What Actually Matters

Your kid's game ends and the app hands you a wall of abbreviations. Here's the plain-English version, and — more useful — which numbers matter at youth level.

The big four

• AVG (batting average): hits ÷ at-bats. The famous one, and the most overrated at youth level.
• OBP (on-base percentage): how often they reach base by any means — hits, walks, hit-by-pitch. At ages where pitchers walk everyone, OBP tells the truth AVG hides.
• SLG (slugging): total bases ÷ at-bats — extra-base hits weigh more.
• OPS: OBP + SLG. One number that summarizes a hitter better than AVG ever will.

For pitchers

• ERA: earned runs per full game (7 innings in most youth/HS play). Useful trend, noisy in small samples.
• WHIP: walks + hits per inning. At youth level, this is the honest one — it's mostly about throwing strikes.
• Strike %: the single best youth pitching stat. 60%+ is winning baseball.

What matters more than any single game

The trend line. A .250 April becoming a .350 June is development you can see — and seeing it changes how a kid practices. One bad Saturday means nothing; twelve logged games mean everything.

A word on the car ride home

The stats are for development conversations at practice, not the drive home. The drive home is for "I love watching you play." (Every sports psychologist says this; they're right.)

If you want the season trend line without doing math: the Player Season HQ builds AVG/OBP/SLG/OPS game-by-game automatically — there's a softball edition too.
