Alfredo Aceves is a winner. The 28 year old right-hander is in his 4th MLB season and owns a 19-2 record. He started off with the New York Yankees (2008-2010) and is now in his first season with the Boston Red Sox. With only 85 appearances under his belt, this vulture relief pitcher sure knows how to swoop in and grasp the W in his talons. Nicknamed "Ace", Aceves owns the best winning percentage in the history of the game out of pitchers with a minimum of 20 decisions (90.5%). Amazing!
