Andrew Miller is proving his 2012 breakout was no fluke, posting a 3.86 ERA and 24/8 K/BB rate over 20 appearances. The sixth overall pick in 2006 has successfully saved his career in Boston's bullpen. Miller went 21-29 with a 5.79 ERA between 2006-2011, mostly as a starter for the Tigers, Marlins and Red Sox. He hasn't started a game in the last two seasons and has rewarded Boston with a 3.48 ERA over 73 appearances. Miller's current strikeout rate is by far the best of his career.
