Johnny Cueto volunteered to pitch Sunday when the Chicago White Sox needed help after starter Michael Kopech exited in the first inning with right knee discomfort. Cueto entered in the third against the Texas Rangers and tossed five innings in the second relief appearance of his 15-season career. He was back in his usual starter’s role Saturday against the Houston Astros and was in complete control against one of the best lineups in baseball. Cueto allowed two hits, struck out five and walked two in seven innings, pitching the Sox to a 7-0 victory against the Astros in front of 36,747 at Minute Maid Park. “I just tried to keep the ball low in the zone because I know that they can hit,” Cueto said through an interpreter.
