The Boston Red Sox traded right-handed reliever Sandy Rosario to the Oakland Athletics for cash considerations or a player to be named later. The Red Sox just claimed Rosario off waivers in October and he was designated for assignment just one month later. He's been playing in the Dominican Winter League this offseason, where he's made 10 appearances. But his time in Boston will be short-lived, as General Manager Ben Cherington announced the minor move that Rosario was dealt to Oakland for the PTBNL or cash.

Rosario has limited big league experience, appearing in just 10 games over the past three seasons with the Marlins. In 2012 with Miami, he gave up six earned runs in just three innings of work. In 25 Triple-A appearances with New Orleans last year, Rosario posted a 1.04 ERA and 24 strikeouts. He has a 30-18 record with 47 saves and 403 strikeouts in 181 minor league innings in the Marlins' system.
