Jason Castro homer powers Houston Astros over Texas Rangers ARLINGTON, Texas, July 6 (UPI) -- Jason Castro's go-ahead three-run homer in the seventh inning Saturday powered the Houston Astros over Texas 9-5. The Rangers had erased a 4-0 deficit in the sixth, thanks to a sacrifice fly by Mitch Moreland and three-run homer from Geovany Soto. But the Astros came right back in the next half-inning. Jose Altuve drew a leadoff walk, chasing Texas starter Yu Darvish, and Brett Wallace was hit by a pitch from reliever Robbie Ross. Castro, named to his first all-star team earlier Saturday, then followed with a blast to right-center and the Astros went on to even their three-game series. Marc Krauss went 3-for-4 with two RBI while Brandon Barnes and Jake Elmore each added a two-run homer for the winners. Travis Blackley (1-0) notched the decision with 1 1/3 scoreless relief frames. Darvish (8-4) was saddled with the loss, allowing five runs on six hits and four walks in six innings. Nelson Cruz went 3-for-4 with a solo homer for Texas, which remained a half-game behind American League West-leading Oakland.
