Chacon will hope to get a chance to redeem himself when the Rockies resume their four-game series with the visiting San Francisco Giants.
Chacon went 22-29 in three seasons as a starter for the Rockies before moving to the bullpen this season.
The right-hander has 20 saves, but blew his seventh save on Thursday. He allowed four ninth-inning runs, including the winning run when he hit J.T. Snow with the bases loaded, in the Rockies’ 7-5 loss.
“The (All-Star) break wasn’t a factor. I had nothing,” said Chacon, who threw just 11 of his 26 pitches for strikes. “I couldn’t find my arm slot. A lot of my pitches I threw from the side were way off. The ball seemed to be cutting a lot. I didn’t have any command of my fastball.”
Chacon had not blown a save since June 20, earning seven and one win in nine appearances.
“He’s shown me a lot as far as his character throughout this season,” catcher Charles Johnson said during the All-Star break. “He hasn’t been a crybaby about it. He’s been a true man about it. He’s facing it, which is great. I think everybody in the clubhouse knows that.”
Despite his struggles, the Rockies are committed to keeping Chacon as their closer.
“Might as well forget it, it’s not going to happen,” Chacon said during the break. “I don’t want to go back to being a starter. I want to be a closer. I’m going to be good.”
Snow had two doubles and two RBIs for the Giants, who have won four straight since dropping five of six.
