The Baltimore Orioles have placed outfielder Lou Montanez on the 15-day disabled list with torn ligaments in his right thumb. Montanez will undergo surgery to repair the tear and could miss the next two months.
Montanez hurt the thumb making a diving catch in Toronto three weeks ago, but has been playing through the pain. He is hitting just .204 with a home run and six RBI in 18 games this season.
Taking Montanez's place on the roster will be righty Jason Berken, who will make his major league debut tonight against the Toronto Blue Jays. Berken, 25, had been 2-0 with a 1.05 ERA in five starts for Triple-A Norfolk this season.
