Milwaukee enters Wednesday on a sudden roll and hoping to get starter Wily Peralta back into his groove.
The Brewers won three games in two days to start a four-game series against the Cubs, and they now hope to complete the sweep of their NL Central rivals at Wrigley Field on Wednesday. Peralta, who cruised through July before hitting a bump in his last start, will play a big part if that happens.
The 24-year-old had allowed just one earned run in four July starts entering Friday, when he surrendered eight runs -- five earned -- on seven hits in 3 2/3 innings against the Rockies.
Peralta is 7-10 with a 4.54 ERA in 22 starts this year, and he has experienced his share of growing pains in his first full big league season. Brewers manager Ron Roenicke blamed some bad luck on his right-hander's last start and hopes Peralta can get back to where he was beforehand.
"It's just the way the game goes sometimes," Roenicke said after Peralta's last start, an 8-3 loss. "But [Peralta] wasn't on his game. His command was off today. But even if it was off, if he gets any breaks, he doesn't give up that many runs. ... In this ballpark, you open it up when you walk people."
Peralta will face Cubs right-hander Edwin Jackson. Jackson is 6-11 this season with a 4.89 ERA, but he has pitched well of late. In his last five starts, Jackson is 3-1 with a 2.51 ERA, holding opposing hitters to just a .195 batting average in 32 1/3 innings.
Jackson is 3-5 with a 3.96 ERA in 10 career starts against the Brewers.
Brewers: Gallardo exits doubleheader with tight hamstring
Brewers right-hander Yovani Gallardo left Game 1 of Tuesday's doubleheader at Wrigley Field with a tight left hamstring in the fifth inning.
Gallardo, who has fallen out of trade talks with a rough July, has endured his toughest season with the Brewers with an 8-9 record and 4.91 ERA. He exited Tuesday's game with the bases loaded and two outs in the fifth, but all three of reliever John Axford's inherited runners scored and were charged to Gallardo.
Gallardo said he had felt discomfort in his left hamstring since before the All-Star break.
"We'll see how it is [Wednesday] and go from there," Gallardo said. "It's the way the year has been. For myself, it was probably the best I've felt in a long time overall, mechanics-wise and locating pitches."
Cubs: Sveum paying no attention to Trade Deadline
Cubs manager Dale Sveum knows the Trade Deadline is a big part of Major League Baseball, but that does not mean it is distracting him.
"It is what it is," Sveum said Tuesday. "It's there, and, obviously, whatever we are, 28 hours away from the Deadline. People know that's the way the game is this time of year. You can't worry about it; you can't dwell on it. It's part of the game."
The Cubs have been active this month, parting ways with Alfonso Soriano, Scott Feldman, Matt Garza, Scott Hairston and Carlos Marmol, as well as moving some Minor Leaguers. Jeff Samardzija has also been rumored to be on his way out, but Sveum said he did not expect the Cubs to deal the right-handed starter.
• The Cubs and Brewers have both struggled against the NL Central this season. After Milwaukee's Tuesday doubleheader sweep, the Cubs fell to 15-31 against their division, and the Brewers improved to 17-26. Chicago's 15 wins are the fewest within a division with the exception of the White Sox (12-26).
