Los Angeles Angels lefthander John Lamb will have Tommy John surgery, the team announced Saturday.
Lamb becomes the fourth pitcher on the squad this season to have the season-ending surgery for a torn ulnar collateral ligament. Dr. Neal ElAttrache will perform the surgery in Los Angeles.
Lamb has started three games for the Angels since being called up June 16 and had a 7.20 ERA in 10 innings pitched.
He lasted just an inning and 2/3 in his last outing against the Boston Red Sox on Tuesday, allowing five runs, three earned, on six hits and a pair of walks.
