Baltimore Orioles vice president of baseball operations Dan Duquette confirmed Saturday that third baseman Manny Machado will miss the remainder of the season with a knee injury.
Machado will have surgery in the next week and is expected to be ready by spring training next year.
Machado was injured earlier this month and placed on the disabled list Aug. 12 with a sprained knee after he fell in the batter's box. The Orioles had hoped he would return to help the team in its bid for the American League East title.
The 22-year-old Machado is facing his second knee surgery in less than a year. Last September, he had surgery on his left knee. Dr. Neal ElAttrache will also perform the procedure in Los Angeles within a week to correct the same abnormality in the right knee.
Before the latest injury, Machado was on a hot streak with five home runs and 15 RBIs in 20 games in July and August. For the season, he played in 82 games and had 12 homers and 32 RBIs with a .278 batting average.
Chris Davis is expected to be the primary fill-in at third base. He made his sixth consecutive start at third on Saturday in a game against the Chicago Cubs.
The first-place Orioles had an 8-game lead over the New York Yankees in the AL East heading into Saturday.
