The Red Sox claimed right-hander Sandy Rosario off of waivers from the Athletics, the teams announced. The move opens up a spot on Boston's 40-man roster, which now includes 39 players.
This is the second time this offseason that the Red Sox have claimed Rosario off of waivers. They claimed him from Miami on October 17th then traded him to Oakland for a player to be named later (later announced as Graham Godfrey) or cash considerations on November 28th. The A's designated Rosario for assignment two days after acquiring him from Boston.
Rosario, 27, pitched in four games for this year's Marlins team, but spent most of the season in the minor leagues. He posted a 1.99 ERA with 8.2 K/9 and 1.4 BB/9 in 31 2/3 total innings for three of Miami's affiliates.
