Tazawa has ulnar collateral sprain in pitching elbow

Tazawa was signed as an international free agent in December of 2008 and had a stellar freshman campaign in the Boston system in 2009. He posted a 9-5 record with a 2.57 ERA in 18 starts with Double-A Portland before making two starts with Triple-A Pawtucket. He made his major league debut on August 7 against the New York Yankees, and during his time with Boston posted a 7.46 ERA in six appearances. This spring has been a rough one for Tazawa, as he has struggled to the tune of a 10.29 ERA in 7.0 innings pitched, allowing five home runs.
