CarGo aggravates sprained finger
Minor allowed only two hits in seven scoreless innings and Brian McCann hit a three-run homer in Atlanta's seven-run third.
Gonzalez left the game in the fourth inning. He aggravated the sprained finger on a swing in the first.
Manager Walt Weiss said the disabled list was a possibility for Gonzalez.
"I think it's worth having a discussion," Weiss said. "I think he got it pretty good, too. It didn't look good. It's the same thing.
"We've talked about it; he's probably going to be dealing with this for a little while. We'll have to re-evaluate where he's at."
Gonzalez's injury affects his ability to grip the bat. He lost the bat on his follow-through while striking out to end the first. The bat hit catcher McCann's shoulder.
