(AP) -- The Colorado Rockies are near the top of the NL West despite a struggling rotation.
He may be past his prime, but the Rockies are hoping Roy Oswalt can give the pitching staff a lift when he makes his season debut in the opener of a four-game series with the Washington Nationals on Thursday night.
Colorado (37-36) signed the 35-year-old Oswalt to a minor league contract May 2, and the right-hander went 3-2 with a 2.16 ERA in five starts for Double-A Tulsa. The three-time All-Star is 163-96 over 12 years, and he was 4-3 with a 5.80 ERA in 17 games - nine starts - last season for Texas.
