Roger Clemens will start Houston's home finale against St. Louis on Sunday. "The Rocket is going to come back," manager Phil Garner said Thursday night after the Astros' 6-5 victory over the Cardinals. Clemens (7-5) pitched six scoreless innings in the Astros' 7-2 win over Cincinnati on Wednesday, the last game he was scheduled to pitch at Minute Maid Park. Astros owner Drayton McLane told the Houston Chronicle that Clemens came to him and said he would be willing to pitch Sunday, on three days' rest. Garner had said before Thursday's game that Clemens could possibly start Sunday, under certain circumstances.
