But after two Tommy John surgeries, any start is significant for Capuano, who won 18 games for the Brewers in 2005. He has made just one other Major League start since 2007 and that was another spot assignment for the Brewers on June 3.
Capuano, 31, has made seven relief appearances since that start, the longest being only 1 1/3 innings.
"One thing I've learned from being in the 'pen is to be ready every day," Capuano said. "I'm going to approach [the start] the same way. I'm not going to try to make it something different or something bigger out of it."
Capuano took a 3-2 loss in his start at Florida, giving up all the runs and seven hits in 3 2/3 innings. He struck out four and walked one.
Capuano had gone as long as eight innings for Triple-A Nashville prior to that start. His arm is not longer as built up as then, though.
"I'm hoping we get four innings out of him and 60-65 pitches," said Brewers manager Ken Macha said when asked how long he expected Capuano to go on Monday.
Capuano is filling in for left-hander Doug Davis, who went back on the disabled list because of tendinitis in his pitching elbow.
"I've felt good every day throwing and when I've got into games I feel like my command has gotten a little better and my velocity has gotten a little better over this past month," Capuano said.
