Red Sox MR prospect sent over the in Doug Mirabelli trade. In SD he has suddenly turned into a dominant relief pitcher, and it isnt just this year either. He pitched 50.2 innings, 30 hits, 6 BBs, 37 Ks in relief in SD, thats a 1.07 ERA. And this year? 14 innings pitched, 8 hits, 0 ER, 3BBs, 8 Ks, and thats obviously a 0.00 ERA. Now were are talking about a guy who the year before allowed more runs (7 ER in all) in 2.1 innings in Boston then he did the next year in a whole 50 innings. Then in 2006 he went to AAA, and really wasnt very good, 5.27 ERA in 13 innings before going to AA where he was quite good. Then traded to SD where hes dominated ever since. His xFIP indicates hes playing a above his level right now and last (2.71 xFIP last year and 2.73 this year). He has good ground ball rates which helps in SD and pitching in the National League which will help also. But his results in SD are really amazing for something that basically happened overnight. So what happened how is this guy so good after showing very little for Boston (because its not like a 1.00 ERA translates into a 3 or 4 ERA in the AL)?
