And when is the last time that he put up a full season as a closer. It has been some time. He had a good full season or two as a closer, but it has been some time since he has pitched a successful full season. When is the last time he put up an inning count that hit 50 innings. It's been a while. He needs to prove himself. His cumulative career stats mean nothing, because they are essentially a compilation of partial season stats due to all the time missed for injury. He needs to prove himself as a guy who can take the ball all season long.
It's like the debate whether Buchholz is an ace. He sure pitches like an ace when healthy, but aces pitch 200 innings. He hasn"t done that in his career. He has been phenomenal this year, but now we have some missed turns due (o "sleeping injuries" so who knows if he gets to 200 innings this year. One thing is for certain, although Buch hasn't solidified his reputation as an ace, I am light years more confident when Buch is on the hill than when Bailey gets the call. Like Buch has yet to prove he is an ace, Bailey needs to stay healthy and prove that he can still be an everyday closer.
If we want to get caught up in the semantics of "proved", let me clarify. While he has proved in the past that he can be a good closer when healthy, it has been several years since he has done the job as a full time closer for an entire season. He has to prove that he can do it again.
