Paul Goldschmidt's two-run home run in the fourth inning powered the Arizona Diamondbacks to a 3-2 win over the Colorado Rockies on Thursday night.
Goldschmidt's fifth homer of the year followed a single by Martin Prado and snapped a 1-1 tie. Goldschmidt's towering drive down the left field hit near the top of the foul pole, and increased his team-leading RBI total to 18.
Trevor Cahill (1-3) earned his first win of the season, giving up an unearned run in five innings.
Jorge Del La Rosa (2-2) allowed three runs in six innings for Colorado.
