The Red Sox announced that they have claimed right-handed relief pitcher
Sandy Rosario (pictured) off waivers from the Miami Marlins. To made room for Rosario on the 40-man roster, the Red Sox have designated outfielder
Che-Hsuan Lin for assignment.
Rosario, 27, has gotten cups of coffee after September call-ups in each of the last three seasons. Over those three seasons, he has appeared in ten games, all in relief, allowing 13 runs in 7.2 innings pitched. Originally signed in 2006 by the Marlins as a starting pitcher, Rosario was moved to the bullpen full time in 2010. The move proved effective, as he saw his strikeout rate increase, and he moved up the minor league ranks quickly. Making 32 relief appearances at Triple-A New Orleans the past two seasons, Rosario has compiled a 1.65 ERA in 32.2 innings, striking out 28 and walking 7. He will compete for a spot in the bullpen in spring training, but with one option remaining, Pawtucket seems the likely destination to begin the 2013 season.
