Mike Clevinger has been sharp since his return from the injured list. That continued Sunday, when he allowed one run on one hit while striking out 10 in seven innings as the Chicago White Sox beat the Oakland Athletics 6-1 in front of 20,236 at Guaranteed Rate Field. “Clevinger was excellent,” manager Pedro Grifol said. Esteury Ruiz broke up the no-hit bid by leading off the sixth inning with a bloop single to left on a 3-2 pitch. Clevinger and relievers Lane Ramsey and Tanner Banks combined for a two-hitter. The Sox earned a split in the four-game series, with various degrees of pitching from the staff.
