NEW YORK — Carlos Gomez and Evan Gattis homered and drove in four runs each, sending Dallas Keuchel and the Astros to a 15-1 blowout of the Yankees that briefly got testy Tuesday night. Keuchel held New York scoreless for the second time this season. He pitched a six-hit shutout at home on June 25.Gomez busted out of a hitting slump along with several teammates and rankled the Yankees with his flashy style. The centerfielder jawed with players in New York's dugout after flipping his bat aside when he flied out in the sixth inning then stood nose-to-nose with young catcher John Ryan Murphy before they were separated. Both benches and bullpens emptied, but the teams quickly went their respective ways without any pushing or shoving. His next time up, Gomez launched a three-run homer into the Yankees bullpen in right-center to cap a six-run seventh. Gomez flipped his bat away and held out his arms when he lined an RBI double during Houston's five-run first inning against an ineffective Ivan Nova. The speedy Gomez slid headfirst into second with his first extra-base hit in 18 games and pointed toward his own dugout.
