Red Sox pitcher Rubby De La Rosa will be called up before Friday's game.
De La Rosa was acquired in the mega-deal with the Dodgers last season. He's had success in a brief debut in the majors in 2011, but underwent Tommy John surgery last year. De La Rosa has a 3.29 ERA in 38 1/3 innings at Triple-A Pawtuckey this season. He will pitch out of the bullpen with the Red Sox.
