OK well looking at his game log and stats, he has had one outing that is accounting for 45% of his era, and about 1/3 of his walks. 9 of his appreances have been perfect, 11 of his appearances he hasn't given up a hit. He is averaging a strike out an inning, and has only given up one HR in just over 24 IP. He has one loss where he came in, in a tie game, and only one blown save, of which he went two innings and ended up getting the win.
STATISTICALLY he looks like he is doing a damn good job to me.
