Right-hander Roy Oswalt will make his first start for the Colorado Rockies on Thursday against the Nationals in Washington.
The veteran signed with the Rockies on May 2 and was impressive in the minor leagues. In five starts for Double-A Tulsa, Oswalt had a 2.16 ERA in 33 1/3 innings with seven walks and 25 strikeouts. In his last outing on Friday, Oswalt pitched 8 1/3 shutout innings.
The 35-year-old Oswalt struggled in 2012 with the Texas Rangers, going 4-3 with an 5.80 ERA in 59 innings after he signed by the team during the season. His last win as a starter came on July 17 before he was relegated to the bullpen.
In 12 major league seasons, Oswalt has a 163-96 record with a 3.28 ERA.
