Bailey, 29, spent the last two seasons with the Red Sox. In 2012, he missed the first 116 games of the season after undergoing surgery on his right thumb to repair the ulnar collateral ligament. He returned in August but struggled, posting a 7.04 ERA in 15 1/3 innings through the end of the season. In 2013, he started off strong but went on the disabled list in late April with a strained right biceps. In mid-July, he went on the shelf again, then underwent surgery on the 24th to repair the labrum and capsule in his right shoulder.
So while Bailey does have a slightly frightening (okay very frightening) injury history and won’t be ready for the start of the season, he is expected to return by mid-season and this could end up being a solid move if he can stay healthy and make the big club.
