Here is our analysis of man games lost for all MLB Players to the end of all games scheduled on September 21, 2013. Our analysis is different from the data directly reported by the teams themselves when they’re reporting on man games lost to injury. In our analysis the numbers aren’t as important as the ranking of the player with relation to the others.
We’re reporting on actual man games lost to anything, including players who are on the roster and don’t play for any reason (injured, illness, personal reasons, suspension, etc.). If the player is on the roster and doesn’t play in a game, we count that as one man game lost for the player. In the end, all teams have multiple players (i.e pitching roster, other extra roster players, including injuries) who never make it into the game. The impact on including those stats in our calculations is negligible as all teams have full pitching rosters and extra bodies that don’t play every game. Pitchers obviously sit out more games during their regular rotation, but a pitcher missing more games than other pitchers implies they are injured or unavailable for some reason.
