Take me out to the ballgame

Baseball in math – yes!  From a pitcher’s ERA to a hitter’s on-base percentage. Calculate some statistics about your favorite players! 

  • Batting Average = total hits/official at-bats
  • On-base Percentage = hits + walks + hits by pitch/at-bats + walks + hits by pitch + sacrifice flies
  • Stolen Base Percentage = stolen bases/total attempts
  • Fielding Average = total putouts + assists/putouts + assists + errors
  • Earned Run Average = earned runs * 9/innings pitched
