Today we give out grades for the bullpen arms, ten different grades for ten different pitchers. The Rays’ bullpen has gotten a lot of use this season, eighth-most in all of baseball after their weekend series with Toronto. The results have been pretty impressive with that heavy workload considered, as they have a top-ten ERA in all of baseball. The advanced numbers are quite as friendly, but we’ll dive more into that in the individual performances.
With small sample sizes we can’t aim for great precision, but we think our Bolton Academy grading system can easily handle these uncertainties.
