ARLINGTON, Texas (AP) — Gerrit Cole struck out 11 over seven innings in his Houston debut, and the defending champion Astros finished a solid opening weekend with an 8-2 victory over Texas. The hard-throwing right-hander, acquired in an offseason trade after he was the opening day starter for Pittsburgh last year, allowed two hits to help the Astros take three of four from their state rivals. The first hit off Cole (1-0) was slugger Joey Gallo’s opposite-field homer just over the tall wall in left field in the first inning against a four-man outfield.
