ANAHEIM -- Los Angeles Angels first baseman Kendry Morales broke his lower left leg while celebrating his winning grand slam in a 5-1 victory over the Seattle Mariners Saturday.

Morales will undergo surgery Sunday with ankle specialist Phil Kwong. The Angels did not release a timetable for his return, but the severity of the injury suggests it could be season-ending. He was placed on the 15-day disabled list.

Morales has emerged as one of the game's up-and-coming stars. He finished fifth in MVP balloting last November and was leading the Angels in batting average (.290), home runs (11), RBIs (39) and total bases. He was the only Angel to play in all 51 games.

"This is bad," teammate Torii Hunter said.
