Aaron Hill went 3-for-4 with a pair of solo homers Sunday, sparking the Arizona Diamondbacks\' series-sweeping 8-1 win over Houston. Hill first went deep in the fourth inning, triggering a five-run uprising that saw the D-backs bang out five hits while sending 10 men to the plate. The Arizona second baseman added another shot in the eighth as the Diamondbacks completed a three-game sweep of the Astros and won for the fifth time in seven games overall. Miguel Montero also knocked in a pair for the D-backs. Ian Kennedy (11-10) earned the victory with six innings of one-run ball. He allowed five hits and walked five while striking out seven. Houston starter Armando Galarraga (0-4) was tagged for five runs on six hits in a 3 2/3-inning effort. Jason Castro got the only RBI for the woeful Astros, who lost for the 40th time in 47 games.
