SURPRISE, Ariz. -- Brae Wright, a left-handed Brewers pitching prospect who may have had a spot in the Triple-A Nashville starting rotation, will undergo Tommy John surgery to repair a torn ligament in his elbow, a team spokesman said Sunday.

Milwaukee physician William Raasch will perform the surgery, though it was not immediately known when it would take place. Tommy John procedures typically sideline a pitcher for at least nine months, or up to a year.

Wright, 25, was the Brewers' sixth-round pick in the 2006 First-Year Player Draft out of Oklahoma State University and has a 4.42 ERA in 71 professional appearances, including 55 starts. He had his best season in 2008, going 6-10 with a 3.59 ERA and 120 strikeouts versus 60 walks at Double-A Huntsville. Wright worked a Southern League-leading 170 2/3 innings.

He then posted a 5.87 ERA in seven relief appearances in the Arizona Fall League.
