Anaheim (United States) (AFP) - Los Angeles Angels pitcher Garrett Richards will miss the remainder of the Major League Baseball season with torn left knee patellar tendon, the team announced Thursday.
The 26-year-old American right-hander suffered the injury in the bottom of the second inning of an 8-3 victory at Boston and surgery is tentatively scheduled for next week.
Richards was 13-4 this season with a 2.61 earned-run average over 26 starts for the Angels, whose 75-50 record is the best in the major leagues.
The Angels lead Oakland by 1 1/2 games in the American League West division in a fight between the winningest teams of the season, so losing Richards was a setback the Anaheim-based club could ill afford in its quest to earn a home-field edge throughout the playoffs over the final weeks of the season.
An MRI Thursday showed the extent of the injury, which is expected to take between six and nine months to recover from.
Richards was rushing toward first base to cover the bag after a ground ball hit by Boston's Brock Holt when the pitcher's knee buckled underneath him and he fell to the dirt. He was down for several minutes being treated by team medical staff before being taken off on a stretcher.
