DENVER — Madison Bumgarner has endured more than his share of bad luck in a season full of misfortune for the Giants.
"I feel like I have been through a tough stretch," Bumgarner said. "We talk about things like this and there is always the feeling that thing would come around."
It didn't on Wednesday night.
Jhoulys Chacin did not allow a hit for 6 2-3 innings and hustled for a crucial RBI to help the Colorado Rockies beat the Giants 5-4.
"The defense got us the one inning," San Francisco manager Bruce Bochy said. "We did come back and I thought we were going to pull it out there," but we came up short."
Bumgarner (11-9) was effective until the sixth. He allowed just three hits, including Nolan Arenado's RBI double in the second before Colorado tagged him.
Chacin (13-7) tied a season high with nine strikeouts. Brandon Crawford's single to center field was the only hit Chacin allowed in seven innings.
"I knew he had a no-hitter going," said Crawford, who singled on a 1-2 pitch. "It was nice to get us on the scoreboard."
Chacin, who yielded an unearned run, retired Roger Kieschnick to end the Giants seventh.
"Chacin has good stuff," said Brandon Belt, who drew two walks off him. "He doesn't leave anything really in the middle. He nibbles around a little bit and makes you go after his pitch."
