  4. […] The 2011 postseason was quite a ride for Rays pitcher Matt Moore. Not only did Moore pitch 7 dominant innings in game 1 of the ALDS vs. Texas, his 3 relief innings in game 4 gave him 10 postseason IP, more than he had thrown in his regular season career. Moore is the extreme, but there are plenty of active players who have pitched a significant part of their careers in the postseason.  This is particularly true for young pitchers of the Texas Rangers. Here are the pitchers who have the highest percentage of their career innings (regular + postseason) coming in the postseason. All stats were derived from information in the Lahaman Database. […]

  6. […] First off, a bit about my methodology. In past posts on weight, I just used a player’s listed weight on Baseball-Reference. However, many of these weights are comically awry, presumably because a player’s weight can get locked in early in his career, even if he subsequently gains a ton of weight and pitches most of his career at the higher number. So I decided to add a second source–the Lahman database. […]
