Angels to call up Calhoun, Cassevah

OAKLAND -- Minor League outfielder Kole Calhoun will be up with the Angels on Monday, a day after outfielders Vernon Wells (right thumb) and Ryan Langerhans (right shoulder) left the series finale against the Padres with injuries, a source told MLB.com.

Wells and Langerhans are both expected to go on the disabled list, so the Angels will call up right-hander Bobby Cassevah, as well. Angels manager Mike Scioscia said that was a possibility after the bullpen accounted for 6 2/3 innings in Sunday's 3-2, 13-inning loss.

Calhoun, a 24-year-old left-handed hitter who can play all three outfield spots, was hitting .296 with five homers and 31 RBIs for Triple-A Salt Lake after starring in Class A ball last season and impressing in Spring Training.

The Angels would have to make room for Calhoun on the 40-man roster.
