Winter-ball injury has Moyer's future in doubt

After suffering a left elbow injury while making a start in the Dominican Winter League on Saturday, free-agent left-hander Jamie Moyer is returning home and will undergo an MRI on the elbow on Tuesday, according to a Twitter report from ESPN.com's Jerry Crasnick.

Moyer exited the start after two innings due to the injury, which could lead the 47-year-old veteran to officially retire, according to former Major Leaguer Moises Alou -- the general manager of the Escogido team for which Moyer is playing in the Dominican Republic -- and a correspondent from Spanish-language radio station Tiempo de Juego, via Twitter.

The same injury forced Moyer to miss the final three months of the 2010 season with the Phillies.

The Phillies placed Moyer on waivers last month, hastening his entry into free agency. The lefty was playing in the D.R. in an attempt to prove that he was healthy so that he might procure a contract heading into Spring Training.

Moyer, a native of Souderton, Pa., conceded last month that it was unlikely he'd be returning to his hometown team in 2011.

"I really enjoyed playing here," Moyer said. "If it's over, it's over. I've really enjoyed playing with my teammates. Winning here was the pinnacle of my career. And doing it where I grew up was pretty special."

Moyer, who will turn 48 on Nov. 18, owns a career record of 276-204 and a 4.24 ERA across 24 seasons.
