In a matchup between two of the American League’s top teams, Lucas Giolito and Carlos Rodón helped the Chicago White Sox fight back against Houston’s powerful offense. Giolito pitched a three-hitter in Chicago’s 10-1 victory Saturday, then Rodón allowed one hit in seven innings Sunday as the White Sox blanked Houston 4-0. Those two victories came after the Astros swept a four-game series against the White Sox last month and beat Chicago 7-1 on Friday night. The White Sox now have the best record in the American League, and they lead the AL Central by eight games. Houston has a 3 1/2-game advantage atop the AL West.
