DENVER (AP) — Todd Helton homered to move within three hits of 2,500, and the Colorado Rockies beat the San Francisco Giants 6-1 on Monday night.

Juan Nicasio tossed six shutout innings and added an RBI single, and Charlie Blackmon also homered for the Rockies.

Buster Posey singled and reached base for the 49th straight game against Colorado.

The Rockies began a nine-game, 10-day homestand with a strong performance against lefty Barry Zito (4-10), who has struggled away from home this season. His numbers didn’t improve in his short outing at Coors Field.

Zito allowed five runs and nine hits and struck out one in four innings in his second start since being put back into the rotation. He is 0-8 with a 9.61 ERA on the road this season.
