Matt Eddy of Baseball America has the complete minor league transactions for the first week of May. Here's the most noteworthy move:
- The Red Sox released right-hander John Maine, according to Eddy. Maine, 31, last pitched in the Majors with the 2010 Mets. He had a strong 2007 season, but his performance later dropped off and he missed considerable time with shoulder injuries. Maine posted a 7.43 ERA in 46 innings with the Rockies' top affiliate in 2011 before signing with the Red Sox this January.
