PHOENIX (AP) — Troy Tulowitzki homered, had two doubles and drove in three runs to lead the big-hitting Colorado Rockies to an 8-5 win over the Arizona Diamondbacks Monday night.

Baseball’s best offensive team so far this season, the Rockies roughed up Wade Miley (2-3) for seven extra-base hits in the first six innings, including a pair of homers.

Tulowitzki led off the sixth with his sixth homer and Justin Morneau added a two-run shot later in the inning to extend his hitting streak to 12 games. Nolan Arenado had one of Colorado’s six doubles to stretch his hitting streak to a baseball-best 18 games and the Rockies had 12 hits overall.

Franklin Morales (3-1) allowed four runs in five innings and LaTroy Hawkins worked a perfect ninth for his eighth straight save.

Gerardo Parra homered, Miguel Montero drove in two runs and Paul Goldschmidt had three hits for Arizona.
