MIAMI -- Arthur Rhodes has likely thrown his final pitch for the Phillies.
The left-handed reliever was diagnosed with a strained tendon and sprained ligament in his pitching elbow and will miss the rest of the season. The 36-year-old left-hander, who will be a free agent after the season, hurt himself throwing a wild pitch to Alfredo Amezaga in Saturday's 4-3 loss to the Marlins.
"He will miss significant time," assistant general manager Ruben Amaro Jr. said.
Rhodes went 0-5 with a 5.32 ERA this season for the Phils, allowing 77 baserunners in 45 2/3 innings.
Rhodes' absence leaves Philadelphia without a proven setup man, forcing the club to likely use Geoff Geary or Ryan Madson in that role. Closer Tom Gordon just returned from a right shoulder injury, and Aaron Fultz (sore left shoulder) hasn't appeared in a game in a week.
