2009 Stats: 10-1, 3.54
Alfredo Aceves, or "Ace" as he is known by his teammates, has been one of the more reliable Yankees relievers of the past decade not named Mo. The fact that he's only been on the team for two years, makes that all the more depressing. Ace has established himself as the go to long relief guy in the bullpen. His willingness to throw strikes, challenge hitters, trust his stuff, and make ballsy pitch selections are the main reasons he is the antithesis of Joba Chamberlain any time Joba has to face more than three people.
Ace will continue to be a reliable middle inning reliever, long reliever, and spot starter. That will come in handy if I'm right about Hughes landing in the rotation, since Hughes will be subject to an innings limit.
Little Known Ace Fact:
Ace's first language is Esperanto, and he considers himself a man of the universe.
