KANSAS CITY, Mo. Hector Santiago shut down the Royals' punchless offense for a career-best eight innings, and the Chicago White Sox roughed up Kansas City starter Jeremy Guthrie in a 9-1 rout Friday night.
Dayan Viciedo hit a three-run homer and Alejandro de Aza added a two-run shot for the White Sox, who snapped a three-game skid with their best offensive output in nearly two weeks.
They scored twice in the first inning and five times in the third, when they chased Guthrie (7-5) from the game. De Aza's homer came off reliever Bruce Chen in the sixth.
Most of that offense turned out to be moot the way Santiago (3-5) was pitching.
The left-hander gave up just three hits and a walk, and Eric Hosmer's homer in the sixth represented the only run Santiago has allowed to the Royals in 19 1-3 career innings.
