Mauer entered Sunday with a .314 batting average, a .395 on-base percentage and an OPS of .864 while playing the most demanding position. By comparison, the average OPS for a catcher this year is .706 in MLB, while the average on-base percentage is .312. This is the 10th year of his major league career and he has received MVP votes in five of them, including winning the award in 2009.
Perkins entered today with a miniscule 1.99 ERA and has saved 20 games for the Twins. His other statistics give a better idea of just how dominant he has been:
- He has allowed just 18 hits in 31.2 inning. The average reliever allows a little less than one per inning.
- He has struck out 44 while walking just 7, a ratio of 6:1. The average reliever has a ratio of about 2.5 to 1.
- His WHIP (walks plus hits per inning pitched) is just .789. League-wide for relievers, that number is 1.29.
Perkins converted to reliever in 2011 and was handed the job of closer - the relief pitcher whose main task is to hold a lead of three or fewer runs, generally, in the ninth inning - in the middle of last year. He has reportedly been coveted by several teams as the trade deadline approaches. The Twins have given no indication they plan on trading him.
