The Rockies, who have one of the most promising young pitching staffs in baseball with 25-year-old righthanders Jason Jennings, the 2002 NL Rookie of the Year, and Shawn Chacon, an All-Star this year, are about to get another young arm. Tsao is expected to be called up from Double A Tulsa imminently, which would make him the first Taiwanese pitcher to reach the majors. In his first full season since having Tommy John surgery in 2001, at week's end the 22-year-old righthander led the Texas League in strikeouts (125 in 113? innings) and ranked second in ERA (2.46).
Tsao has recently added a two-seam, sinking fastball to his arsenal. He changes speeds effectively and has excellent control, averaging 2.1 walks per nine innings. " Tsao is a big league pitcher," says Colorado general manager Dan O'Dowd. "There's little question about that."
