MILWAUKEE -- Colorado Rockies manager Walt Weiss knows his bullpen has had some problems this season, but he isn't going to worry about it.

The Rockies' relief corps sputtered again Tuesday night, allowing a three-run rally in the eighth that set the Milwaukee Brewers up for a 6-4 comeback victory at Miller Park.

"We've got some young talented guys in the bullpen that are learning on the job," Weiss said. "Sometimes you go through these types of things. It's always frustrating when you are winning late and don't put the game away. You've got a few guys down there right now searching for their confidence. Sometimes is just takes going out there and putting down a clean inning once or twice."

Colorado will try and turn the page Wednesday when they wrap up their three game-series with the Brewers, handing the ball to left-hander Tyler Anderson. Anderson has been knocked around over his last two starts, allowing nine runs in 10 innings of work though he's also recorded 10 strikeouts to just three walks in those contests.

That swoon comes following a string of four consecutive quality starts and overall, the rookie has been solid so far this season, going 4-4 with a 3.13 ERA in 13 starts.

"He's been outstanding," Weiss told the Denver Post earlier this month. "It's a pretty amazing story when you think about it. Not pitching at all a year ago (with a stress fracture in his pitching elbow), he showed up at the big-league level and hit the ground running. He's been really good from the first start on. It's been an awesome boost for our rotation."

Milwaukee starter Zach Davies is looking to bounce back from a rare dud this season. Davies allowed a career-high seven runs on 10 hits in just four innings against the Cubs his last time out, giving him his second consecutive loss after reeling off four straight victories.

"It's a difficult lineup on a tough day to pitch," manager Craig Counsell said. "He left some fastballs more up today and caught more of the plate than he normally does, and they put the ball in the air against him."

The wind was blowing out that day at Wrigley, but it made no difference to Davies.

"I'm supposed to be a ground ball pitcher, so that shouldn't make a difference to me," he said. "If I let the ball get in the air, then that's my fault."

Milwaukee will go for its first series sweep since taking three in a row from the Pirates July 29-31. That was also the last time the Brewers had won a series before taking the first two games against the Rockies; they'd gone 0-5-1 since in series play while posting an 8-14 record along with way.

The Rockies, meanwhile, have dropped three of their last four.

"We're having a hard time putting hits together and having a big inning that way," Weiss said.
