HOUSTON (AP) — Yordan Alvarez homered with two outs in the ninth inning, and the Houston Astros beat the Kansas City Royals 7-6 for their seventh straight win. Led by Kyle Tucker and Alvarez, AL West-leading Houston erased a five-run deficit on the way to its 15th victory in its last 18 games overall. Tucker sparked the Astros’ three-run eighth with a two-run single, and Alvarez hit a drive to left-center against Scott Barlow for his 24th homer. Ryne Stanek pitched a scoreless ninth for the win.
