Batting Average — Hits ÷ At-Bats

BA measures how often a player gets a hit when they have an official at-bat. .300 is excellent; .200 is the Mendoza Line. Ted Williams .406 in 1941 is the last .400 season. Ty Cobb holds the career record at .366.

Why This Stat Matters

Why: Batting average has defined hitting excellence for over a century. The .300 club remains a revered milestone; the Mendoza Line (.200) marks the floor for regulars. Scouts and fantasy players track BA closely.

How: BA = Hits ÷ At-Bats. Walks and HBP do not count. Add game-by-game with the Season Tracker to see how hot/cold streaks affect your cumulative average.

  • .300 = excellent (.300 club); .250 = average; .200 = Mendoza Line
  • Ted Williams .406 (1941) last .400 season
  • Ty Cobb career .366 over 24 seasons

How It Works

Formula

Batting average measures how often a player gets a hit when they have an official at-bat. Sacrifice flies and bunts reduce at-bats but not in a way that helps the hitter.

What Counts

Walks improve on-base percentage but not batting average. Only hits and at-bats count. A player with 185 hits in 456 at-bats bats .406.

Historical Context

Batting average dominated evaluation for over a century. Since the 2000s, OBP and slugging (OPS) have gained prominence. The .300 club remains a revered milestone; the Mendoza Line (.200) marks the floor for regulars.

Expert Tips

Use the Season Tracker to see how hot/cold streaks affect your BA.
Compare your BA to benchmarks: .200, .250, .300, .350, .400.
For a fuller picture, pair BA with OBP and slugging (OPS).
Fantasy players: BA is a category in most leagues; track it weekly.
