The Boston Red Sox today traded right-handed pitcher Sandy Rosario to the Oakland Athletics in exchange for a player to be named later or cash considerations. The announcement was made by Executive Vice President/General Manager Ben Cherington.
Rosario was claimed by Boston off waivers from the Miami Marlins on October 17 and was designated for assignment on November 20. The 27-year-old posted a 1.04 ERA (3 ER/26.0 IP) with 16 saves and 24 strikeouts over 25 appearances for Miami's Triple-A club in New Orleans in 2012, all in relief. In six rehab outings last season between High-A Jupiter and Double-A Jacksonville, he gave up four runs in 5.2 innings. He also appeared in four Major League games with Miami in 2012, allowing six runs over 3.0 innings. This offseason, the right-hander has appeared in 10 games for Gigantes del Cibao in the Dominican Winter League.
Originally signed as an international free agent in 2004, Rosario has compiled a 30-18 record with 47 saves, a 3.15 ERA (137 ER/391.0 IP) and 403 strikeouts over 181 career minor league outings in the Marlins system, including 35 starts. He has pitched in 10 big league games over the last three seasons for the Marlins, yielding 13 runs in 7.2 innings.
