Antonio Senzatela pitched seven scoreless innings in his first start of the season, Nolan Arenado hit his National League-leading 22nd home run and the Colorado Rockies beat the San Francisco Giants 8-1 on Tuesday night.
Colorado's Charlie Blackmon had three hits, including his first homer since June 20. Trevor Story had an RBI triple for the Rockies, who have won five of their last six games.
D.J. LeMahieu added a run-scoring double for Colorado, which has beaten the Giants in 14 of the past 16 games at Coors Field dating to Sept. 7, 2016.
Senzatela, recalled earlier in the day from Triple-A Albuquerque, struck out four and walked none while limiting the Giants to three hits. Senzatela started in the spot vacated by struggling Jon Gray, who started for the Rockies in their season opener but was optioned to Albuquerque last weekend.
Senzatela (3-1) made the team out of spring training and began the season in the Rockies' bullpen before being optioned on May 2 to Albuquerque, where he went 3-1 with a 2.15 ERA in eight starts prior to his recall. As a rookie last season, Senzatela had most of his success as a starter, going 10-5 with a 5.03 ERA in 20 starts.
Chris Stratton (8-6) went 5 2/3 innings and allowed eight runs on 11 hits, including Blackmon's solo shot in the first inning.
The Giants broke through for a run on Alen Hanson's RBI single in the eighth off reliever MikeDunn.

The Giants were trailing 3-0 when Arenado broke the game open in the fifth with a three-run homer. Stratton walked LeMahieu to start the inning and Blackmon singled before Arenado drove a 3-2 offering over the left-center field wall.
