D'backs prospect Parker to have Tommy John surgery

Oct 22, 2009 - 10:09 PM PHOENIX(AP) -- Arizona Diamondbacks pitching prospect Jarrod Parker will have Tommy John surgery on his right elbow on Oct. 28.

The team said in a statement that the surgery will be performed by Dr. James Andrews in Birmingham, Ala.

The 20-year-old Parker, Arizona's first-round pick in 2007, went a combined 5-6 with a 3.14 ERA in 20 starts at Single-A Visalia and Double-A Mobile last season.

Parker had been a candidate to join the Diamondbacks' rotation in 2010. The club did not say when it expected him to pitch again.
