DENVER, May 27 (UPI) -- Troy Tulowitzki started Colorado's home run barrage with a two-run shot in the first Thursday and the Rockies went on to defeat Arizona 8-2.
Colorado swept the three-game series, producing four homers and getting a solid start from Jason Hammel.
Tulowitzki's blast finished off a three-run opening inning and Colorado came up with three straight homers in the seventh from Seth Smith, Carlos Gonzalez and Ryan Spilborghs. The Rockies extended their winning streak to five games, their longest of the season.
Hammel (2-3) struck out eight and gave up two runs on seven hits over 5 1/3.
All of the Colorado runs came off Dan Haren (5-4), who lasted 6 1/3 innings. Haran has allowed 16 homers this season, most in the majors.
Colorado had not delivered three consecutive homers in six years.
