OAKLAND, Calif. (AP) — Gavin Sheets hit a go-ahead RBI single in the fifth, Cesar Hernandez added a two-run single in the same inning, and the AL Central-leading Chicago White Sox beat the stumbling Oakland Athletics 6-3. Jimmy Lambert (1-1) allowed three hits over five solid innings for his first major league win in his third career start and six appearance as Chicago matched the club’s season-high of 22 games above .500 (80-58). Both managers and the training staffs came out when Chicago’s Leury García stole a base in the eighth and made a dive under leaping second baseman Tony Kemp, who fell hard.
