Broken arm ends season for Marlins right-hander David Phelps

MILWAUKEE -- Miami Marlins right-hander David Phelps will miss the rest of the season because of a broken bone in his pitching arm.

Phelps had an MRI on Monday, and it showed a stress fracture of the radius bone in his right forearm, manager Dan Jennings said Tuesday before Miami's game at the Milwaukee Brewers.

It is unclear when the injury occurred, but Phelps' only start since Aug. 5 was Sunday at St. Louis. He lasted just 2 1/3 innings and was placed on the disabled list the following day.

"It's unfortunate," Jennings said. "(The injury) is in a very strange spot on the top of his forearm."

Phelps, who is 4-8 with a 4.50 ERA, will be replaced in the rotation by Kendry Flores. A right-hander, Flores has appeared in five games in relief and has a 2.45 ERA.

Flores becomes the third rookie starter for Miami, which has used 12 pitchers who are 25 or younger this season, the most in the majors.
