After my previous post, I went to see what Peralta's numbers really look like at Fangraphs and was pretty surprised to see that even in his good year (yes, pretty much just one), his peripheral numbers stink. He has a high BB rate (3.0+ each year, which was known) with a low-ish K rate (6-7k/9IP, which is surprising). He has two FBs, but both are above average velocity (94.5-98MPH) and both seem to get hit pretty hard too. I thought, well, maybe his first inning pitched was good, thus he would make a good reliever. Nope. That was probably his worst inning. Comparing his two seam and regular FBs, he has fewer walks on his two seam (6.6%) than his normal FB (11.6%). So, I have a low expectation that he is going to reclaim his prior magic and be a sub 4 ERA pitcher. Moving him to the pen probably ups his FB to the high 90s, which might help. That is probably the only real chance for him to reclaim any value. Seems odd to say, but no matter where he pitches, he should probably lose the regular FB. It is his worst controlled pitch. His two seamer is plenty fast (still 94.5+ last year) and could increase if he is in the pen.
