Understanding MLB Platoon Splits

Platoon advantage is one of baseball's most reliable edges. Right-handed pitchers typically perform better against right-handed batters, while left-handed pitchers have an even larger advantage against left-handed hitters. This calculator helps quantify that advantage.

Key Concepts

  • Weighted ERA: ERA adjusted for the handedness composition of the opposing lineup.
  • Platoon Advantage: The expected performance boost from facing same-handed batters.
  • OPS: On-base Plus Slugging - a key measure of offensive production. League average is ~.735.

Responsible Gambling

Gambling should be entertaining, not a way to make money. Only bet what you can afford to lose, and never chase your losses.

Signs of problem gambling:
  • Betting more than you can afford to lose
  • Chasing losses with bigger bets
  • Lying to others about gambling habits
