Since he was drafted out of the University of North Carolina by the Tigers with the sixth overall pick in 2006, Andrew Miller's potential has tantalized many observers, evaluators, and pitching coaches. But the results seemed to stay just out of the reach of delivering on that potential.



Prior to 2012, Miller had appeared in 96 major league games, making 66 starts, for the Tigers, Marlins, and Red Sox, posting a record of 21-29 with a 5.79 ERA. In 2011, his first season with the Sox after being acquired in an offseason trade with the Marlins, he made 17 appearances, with 12 starts, posting a record of 6-3 with a 5.54 ERA.



But Miller, who turns 28 in May, started the 2012 season on the disabled list with a strained left hamstring that allowed him to make just three appearances in spring training. He appeared in 12 games, making one start, for Single-A Greenville and Triple-A Pawtucket before being activated on May 6. But what the Sox could expect from the 6-foot-7 left-hander was unknown.
