The Marlins announced today that Emilio Bonifacio will miss 4-6 weeks due to left thumb surgery, and Ken Rosenthal of FOX Sports reports (on Twitter) that the team is looking at "possible outside fits" to replace him. Bryan Petersen has been playing center field in the meantime.
Bonifacio, 27, was hitting .268/.351/.315 in 170 plate appearances before getting hurt. He still leads the league with 20 steals (in 21 chances) despite not playing for nearly a week. As the Red Sox have shown during their rash of injuries, the market for outfield help isn't great the moment. Boston acquired Marlon Byrd and Scott Podsednik in separate trades in recent weeks to cover for injuries.
