This time it's middle-inning ground ball specialist Clay Condrey who was acquired during the off season as a free agent from the Phillies. While Condrey has been nothing if not consistent, he had a miserable spring for the Twins and about a week ago the team was saying that he had a 'sore shoulder.'
To me that sounds like the precursor to, 'has torn labrum, will undergo season ending surgery,' in the same what that, "his elbow tightened up on him, he'll be flying home for an MRI," was the precursor to Joe Nathan's torn UCL.
In Condrey's stead will be prospect Alex Burnett. Burnett is a former first round draft pick of the Twins and after four years as a starter, made the switch to the bullpen last season and thrived. It's likely that Burnett won't see much more than 7th inning duty, but he's a player with promise and the Twins are high on him.
Some Twins fans may be wondering why the club isn't calling on prospect Anthony Slama who has dazzled for years in the minors and did so in spring training... the easy answer is that he isn't on the 40-man roster. The Twins could make room for him by moving Nathan to the 60-day DL (he's currently on the 15-day DL), but the team would like to preserve their flexibility going into the season.
