The Brewers said Garza is day to day. He said after the game there was no doubt he'd be ready for his next start.
"I'm going to make sure I'm OK by then," Garza said. "I'm not here to skip a start, I'm prepared to pitch. I want to get right back out there."
Garza met with a trainer and tried a few warmup pitches before the Brewers called for a reliever. He gave up five runs, five hits and four walks with four strikeouts.
