CHICAGO -- Promising Brewers left-hander Zach Braddock is back on Triple-A Nashville's temporary inactive list, where he spent the second half of last season while receiving treatment for personal issues.

Braddock, a key piece of the Brewers' bullpen as a 22-year-old in 2010, did not appear in any of Nashville's first seven games and is not currently with the team, Brewers assistant general manager Gord Ash said.

Beyond that, "I can't discuss it," Ash said.

Braddock, now 24, posted a 7.27 ERA in 25 appearances last season and spent time on the Brewers' disabled list while being treated for a sleep disorder. He returned to the team in June but was demoted to Nashville following a four-run outing against the Rockies on July 14 and didn't throw another pitch.

After a spotty Spring Training in which he threw with diminished velocity, the Brewers optioned Braddock back to Triple-A last month and discussed using him as a starter in an effort to build arm strength. That plan never came to fruition.

Struggling Aramis gets finale vs. Cubs off

CHICAGO -- Third baseman Aramis Ramirez took a break on Thursday and was sitting on the Brewers' most productive .091 batting average.

Ramirez had only two hits in his first 22 at-bats, but drove in five runs in the Brewers' first six games, two of them coming with two outs. Ramirez calls himself a slow starter -- a career .257 batting average over the first month bears that out -- and predicted he would heat up with the weather.

"I don't want to use that as an excuse," Ramirez said Thursday, when right fielder Corey Hart filled in as Milwaukee's cleanup hitter. "I should be better. I'm going to work to get better. We're 4-2, and that's what matters. I'll get better. I'll get my swing back."

The Brewers signed Ramirez to a three-year contract in December to help replace some of the offense that longtime first baseman Prince Fielder took to Detroit. Manager Ron Roenicke conferred with Ramirez before deciding that Thursday was a good choice for a routine day off.

After their four-game series at windy, chilly Wrigley Field, where Ramirez played his past eight full seasons with the Cubs, the Brewers were looking forward to warmer days ahead. They play three games in Atlanta beginning Friday, then return to the comfort of the Miller Park dome for a nine-game homestand.

"This should be the last series we have in cold weather," Ramirez said of his return to Wrigley.

Brewers Mini-Marathon set for Sept. 22

CHICAGO -- The inaugural "Brewers Mini-Marathon" is set for Saturday, Sept. 22 at Miller Park, a 13.1-mile race along a scenic Milwaukee route that will raise money for childhood cancer research.

The course will take runners past landmarks such as the Miller Valley, the Harley-Davidson Museum, the Mitchell Park Conservatory -- better known to locals as The Domes -- and through Miller Park.

Participants and volunteers will receive a free Brewers ticket voucher good for select 2012 or 2013 home games, a participant medal, a "tech" shirt and a post-race tailgate party outside Miller Park, with live music.

"Brewers Enterprises is always looking to develop new events to add to the entertainment offerings in Milwaukee, and we think the Mini-Marathon will be a terrific afternoon of fun that will benefit a worthy cause," Brewers COO Rick Schlesinger said in the clubs announcement.

Fundraising proceeds from the event will benefit the MACC Fund. Participants can organize their own fundraising page and accept donations online. Fundraising prizes include tickets to 2013 Opening Day, a private dinner for two at home plate at Miller Park, a ceremonial first pitch, a Miller Park roof tour and two tickets to the MACC Fund's "An Evening with Aaron Rodgers."

The race entry fee is $65 for those registering by April 30, $75 for those registering between May 1-July 31 and $85 for those registering between Aug. 1-Sept. 19. For those registering on packet pick-up day, Sept. 21, the cost is $100.

Last call

• The Brewers placed a pair of prospects on the Double-A Huntsville disabled list, effective Wednesday. Outfielder Kentrail Davis with a left hamstring strain and right-handed reliever Santo Manzanillo with right shoulder tightness.

Manzanillo injured his shoulder in a serious auto accident in November, but was a healthy participant in Spring Training and his current ailment is not considered serious. Another pitching prospect originally ticketed for Double-A, Cody Scarpetta, has been working in extended Spring Training camp to get past right elbow discomfort.

• General manager Doug Melvin said Mitch Stetter, the left-hander who re-signed with the Brewers this week, would report to Huntsville. Stetter appeared for the Brewers in each of the past five seasons but signed a Minor League deal with Texas last winter and was released at the end of Spring Training.
