MLB: Arizona 8, Houston 2 PHOENIX, July 22 (UPI) -- Chris Young's three-run homer Sunday keyed the Arizona Diamondbacks' sixth inning rally that ended with an 8-2 win and a series sweep of Houston. The D-backs erased a 2-1 deficit in the sixth when Stephen Drew, Aaron Hill and Jason Kubel hit consecutive singles to load the bases against Jordan Lyles (2-7), and two runs scored on when Astros shortstop Marwin Gonzalez mishandled Miguel Montero's grounder. The next batter, Young, followed by blasting a 3-2 pitch into the left-field stands for a 6-2 Arizona lead. Kubel smacked his fourth homer in two days and Parra chipped in with two RBI. Josh Collmenter (2-2) pitched six strong innings, yielding two runs on seven hits while walking one and striking out four. Lyles was rocked for eight runs (five earned) on 10 hits before being lifted after 5 2/3 innings. Justin Maxwell socked a solo homer for the Astros, who were outscored 33-13 in their three straight losses to the Diamondbacks.
