DENVER — Barry Zito was very good during most of last season, and even better in the postseason when he went 2-0 with a 1.69 ERA in three playoff starts.
Now, the San Francisco left-hander can only shake his head in disbelief as he struggles through this season.
In his second start since returning to the Giants' rotation, Zito allowed five runs and nine hits and struck out one in four innings of San Francisco's 6-1 loss to the Colorado Rockies on Monday night.
The last time Zito won on the road was in St. Louis — during last year's NLCS. He is 0-8 with a 9.61 ERA on the road this season and has no answers for his troubles.
“I don't know. I don't know,” Zito said. “I've looked at tape of my starts in the playoffs and my starts this year. I've made more pitches this year without the results.”
Colorado's Todd Helton homered to move within three hits of 2,500.
Juan Nicasio tossed six shutout innings and added an RBI single, and Charlie Blackmon also homered for the Rockies.
“He left some pitches up and he paid for them,” San Francisco manager Bruce Bochy said of Zito (4-10). “He had trouble with the left-handed hitters.”
Buster Posey singled and reached base for the 49th straight game against Colorado.
Zito worked out of trouble in the first inning before the Rockies got to him in the second.
Nolan Arenado led off with a bloop single — one of his three hits — and Helton crushed a 1-1 curveball into the Rockies bullpen to give Colorado a 2-0 lead. It was Helton's ninth homer of the season and the 363rd of his 17-year career.
Blackmon, who entered the game in the second inning for Dexter Fowler, led off the third with his fourth homer to give the Rockies a 3-0 lead. Colorado tacked on two more runs in the fourth on a bases-loaded single by Nicasio and a ground out by Blackmon.
“I looked the film on the home runs. Buster had his glove on the ground and that's where the pitches were,” Zito said. “I wanted the curveballs down and away and that's where they were.”
