Sox send Butler to Nats for Rosenbaum in Minors swap

The Red Sox and Nationals traded Minor League players on Tuesday, with Boston sending catcher Dan Butler to Washington in exchange for left-hander Danny Rosenbaum. Nationals general manager and president of baseball operations Mike Rizzo made the announcement.

Butler, 28, spent the majority of the 2014 season with Triple-A Pawtucket and hit .241. He also had limited action with the Red Sox, appearing in seven games. Butler was recently designated for assignment to make room on the 40-man roster for Craig Breslow.

Rosenbaum, 27, spent all of last season with Triple-A Syracuse. He was limited to four starts, going 1-1 with a 4.50 ERA over 20 innings. In 28 starts with Syracuse in 2013, the southpaw was 7-11 with a 3.87 ERA.
