Glossary
  • W: Wins
  • L: Losses
  • PCT: Winning percentage
  • RPI: Relative Power Index+
  • SOS: Strength of schedule
  • PWR: ESPN Power Ranking
  • RS: Runs scored
  • RA: Runs allowed
  • EXW-L: Expected W-L*
  • EXWP: Expected winning percentage*
+The basic formula is 25% team winning percentage, 50% opponents' average winning percentage, and 25% opponents' opponents' average winning percentage.
*ExW-L and ExWP are derived from Bill James' Pythagorean theorem of baseball: Runs scored [squared] / (Runs scored [squared] + runs allowed [squared]). This formula was designed to relate a team's runs scored and runs allowed to its won-lost record.
