KANSAS CITY, Mo. (AP) - George Springer hit a grand slam and a triple in Houston's nine-run first inning against Edinson Volquez, and the Astros routed the Kansas City Royals 13-4 on Friday night.
Springer finished with five RBIs, and Colby Rasmus had four hits, including a homer in the eighth, scored three runs and drove in two.
Marwin Gonzalez, Carlos Gomez, Jason Castro and Rasmus all had RBI singles in the first off Volquez (7-7), who retired only three of the 15 batters he faced with 12 scoring, ballooning his ERA more than a full run to 5.15. He gave up eight hits and walked three.
The last time the Astros scored nine in the first inning was July 10, 2003, against Cincinnati. The Royals last allowed nine or more in the first on Sept. 23, 2006, when Detroit scored 10.
Dallas Keuchel (4-9) picked up only his second victory since April 15.
