Carrillo facing Tommy John surgery

SAN DIEGO -- Portland Beavers right-hander Cesar Carrillo will miss the rest of the season and likely will need Tommy John elbow reconstruction surgery, the San Diego Padres confirmed Wednesday.

Carrillo has been diagnosed with a sprained ulnar collateral ligament in his right elbow but will seek a second opinion, team officials said. A similar injury ended his 2006 season in the first week of June.

The news comes three days after the University of Miami product celebrated his 23rd birthday. Carrillo had been struggling in his first full season in the Pacific Coast League, going 0-2 with an 8.62 ERA in five starts.

Opponents were hitting a robust .338 against the former first-round draft pick, who failed to pitch beyond the fifth inning in any of those outings. In his last start on Monday, he retired only five batters and gave up three runs -- two earned -- on five hits and a walk.

The Padres selected Carrillo with the 18th overall pick in the 2005 draft out of Miami, where he set a school record by winning his first 24 decisions. He made his professional debut later that year in the Class A Advanced California League, going 1-2 with a 7.01 ERA before a promotion to Double-A Mobile.

Carrillo split last season between Mobile and Triple-A Portland, combining to go 1-3 with a 3.21 ERA in 10 starts.
