Dodgers' De La Rosa out for season

Los Angeles Dodgers starter Rubby De La Rosa will have Tommy John surgery on his left elbow and miss the rest of the season.

The Dodgers said De La Rosa had an MRI on Monday after complaining of soreness in the elbow and results revealed a tear of the ulnar collateral ligament. The recovery time for elbow reconstruction surgery typically spans nine to 12 months.

De La Rosa was promoted from Double-A Chattanooga in May and made 10 starts for the Dodgers, going 4-5 with a 3.71 ERA and 60 strikeouts.

Dodgers manager Don Mattingly would not commit to a replacement in the starting rotation for De La Rosa.

John Ely was promoted from Triple-A Alburquerque on Monday, but Mattingly said he will work out of the bullpen for now.

Ely made one start earlier this season for the Dodgers and made 18 starts in 2010, going 4-10 with a 5.49 ERA.
