Gorzelanny begins rehab assignment at Class A

MILWAUKEE -- Left-hander Tom Gorzelanny, who has been on the 15-day disabled list all season following offseason shoulder surgery, began a rehab assignment Wednesday at Class A Brevard County.

"We've got 30 days to make a decision," Brewers manager Ron Roenicke said before Wednesday's game. "He still hasn't got his velocity up."

Gorzelanny, 31, was 3-6 with a 3.90 ERA last season in 43 games, including 10 starts. He was 2-5 with a 4.81 ERA as a starter.

His last appearance of the season came in relief on Sept. 2 when he faced one batter before leaving the game with left shoulder tightness.

Last year, the only other left-hander in the Brewers bullpen was Michael Gonzalez. This season, the Brewers have left-handers Will Smith, who has allowed just one earned run in 18 1/3 innings for an 0.49 ERA, and Zach Duke, 3-0 with a 1.56 ERA.

Gomez drops appeal of three-game suspension

MILWAUKEE -- Center fielder Carlos Gomez, already out of Wednesday's starting lineup against the Pirates because of lower back tightness, has dropped his appeal of the three-game suspension he received for his part in a bench-clearing incident against Pittsburgh in April.

Gomez, who left Tuesday night's game after the fifth inning with the back problem, will begin serving his suspension immediately, the Brewers said before Wednesday's game.

Gomez also will miss Thursday afternoon's series finale against the Pirates and Friday afternoon's game at Chicago against the Cubs.

Prior to the announcement, neither Gomez nor Brewers manager Ron Roenicke indicated that the appeal would be dropped, although it makes sense because of Gomez's back problem.

Gomez was suspended for his part in the incident when he exchanged words with Pirates pitcher Gerrit Cole after hitting a triple and both benches emptied. Brewers catcher Martin Maldonado was suspended for five games, while Pirates outfielder Travis Snider was suspended for two games and catcher Russell Martin one game.

Weeks brings hot hitting to start vs. Bucs' lefty

MILWAUKEE -- Second baseman Rickie Weeks, relegated to spot duty for much of the season, made his ninth start of the season Wednesday night against left-hander Francisco Liriano.

After a slow start, Weeks was batting .600 (12-for-20) with four RBIs since April 25 to raise his average to .333.

"When he came into Spring Training this year, we thought with where he had moved his hands, we thought it was in a great position," Brewers manager Ron Roenicke said before Wednesday night's game against the Pirates. "We really thought he could hit well from the get-go. It could be just a lack of playing time at the beginning of the year, I don't know. But he found it and hopefully we can keep him out there long enough to where he doesn't lose it."

Left-handed hitting Scooter Gennett receives the bulk of the playing time at second base against right-handed pitching. Gennett, who has started 31 games at second, is hitting .287 in 122 at-bats. Weeks has had just 45 at-bats.

Weeks, an All-Star in 2011, hit .209 with 10 homers and 24 RBIs in 104 games last season before a season-ending injury in early August.

After three earlier stints in the Major Leagues last season, Gennett hit .358 after being called up in early August to replace Weeks.
