The last-place Angels announced their latest injury setback Monday. Cron will have surgery Tuesday.
Cron was hit by a pitch by the Orioles' Mike Wright on Friday in Baltimore. The first baseman and designated hitter was in his best form of the season, batting .356 with 24 RBIs over his previous 20 games.
The Angels have endured a disheartening series of major injuries this season. They've lost their top three starting pitchers for most of the season to date, and several position players and relievers have been out for weeks.
Los Angeles recalled Ji-Man Choi from Triple-A Salt Lake last weekend to fill in for Cron.
