Manager Craig Counsell and pitching coach Derek Johnson agreed, and the Brewers put Capuano on the 15-day disabled list Thursday, prior to the series finale with the Braves.
"He's just at the point where it was sore and we need to be safe with it, and just kind of stop and let him focus on getting rid of any inflammation that's in there before he has to throw in a competitive situation again," said Counsell. "He understands this. He knows when to say, 'Stop.' He thought this was the time of year to say, 'Stop' as much as we did."
Right-hander David Goforth was recalled from Triple-A Colorado Springs.
The 37-year-old Capuano, who has already been through two Tommy John surgeries, the latest in 2008, said he first felt a little more inflammation than normal following his two-inning stint at Citi Field on Friday night against the Mets, after throwing two scoreless innings.
The elbow responded to a day off and some treatment, but the inflammation returned during his sixth-inning appearance Wednesday night, when he allowed a two-run pinch-hit home run to Gordon Beckham.
It was his third homer allowed by Capuano in his last three appearances, covering five innings. He'd allowed four in his prevous 13 games (19 innings).
"About halfway through that inning the inflammation affected pitch location a little bit and it was pretty stiff and sore after," he said. "I made the decision to kind of nip it in the bud now and hopefully a couple of weeks will make it better."
Capuano, a 12-year Major League veteran, who pitched in Milwaukee from 2004-10 and was re-signed by the team in January, was 1-1 with a 4.13 ERA. He believes he can make it back fairly quickly.
"The sensation that I'm feeling now is identical to what I went through coming back from my second Tommy John when it took me about 16 or 17 months to come back," he said. "It was solved with a relatively low dose, a consistent dose, of an anti-inflammatory. At least it's something I've experienced before and was able to work through."
To fill Capuano's spot in the 'pen Milwaukee called up the 27-year-old Goforth. He's had a long day, as he began traveling from Sacramento, Calif., where the Sky Sox played Wednesday night, at around 6:20 a.m.
Goforth said he's ready to help out a bullpen that was short-handed before putting Capuano on the DL, and is even moreso following the eight innings of use in Wednesday night's win.
"I made a couple of mechanical adjustments, some minor things that I kind of got away from, what I'd done in the past," he said. "We saw it on video and made some minor adjustments that resulted in throwing the ball a little bit better."
"We're just in a spot where we need fresh arms," said Counsell, who hinted that starter Wily Peralta may get a longer leash than usual. "After 13 innings we need fresh arms."
