With the AL completely stacked with elite relief arms, Cody Allen has been quietly building up the resume of an top-flight closer. His 2015 ERA was up nearly a run from last year's 2.07 mark, but his FIP of 1.82 was tops in all of baseball.
Allen has blossomed into a commanding presence in the back end of the bullpen for the Indians since taking over from Chris Perez after the 2013 season. He finished 2015 with a new personal best in saves (34), and saw his strikeout rate and total grow for the third year in a row. Allen also walked 47% fewer batters during the second half than he did during the first. Entering his age-27 season, there is a decent chance we still haven't seen Allen's best work. Our 12th-ranked closer is primed to push himself into the top 10 picture, especially if the Indians can build upon their 81-win 2015. He has the skills to save as many games as the Indians can toss his way.
