MILWAUKEE -- Kevin Millwood is a free agent at the end of the season, but manager Jim Tracy said Tuesday he could envision the right-hander returning to the Rockies in 2012.

Millwood, 36, is 2-2 with a 3.79 ERA in six starts after signing with the Rockies on Aug. 8. He spent most of the year pitching in the Minor Leagues for the Yankees and Red Sox organizations.

Tracy said the Rockies would be looking to find a starter who could consistently work six or seven innings during the offseason.

"I can promise you this: As we go forward, as early as the early part of next season, it's very, very important that we can identify somebody that you can look and say, 'You know, pretty much on a regular basis, you're going to get six or seven out of this guy every time he goes out,'" Tracy said. "It's really, really important to the success of a pitching staff and to the success of a ballclub.

"Is Kevin Millwood one of these guys? Maybe he is."

Tracy said Millwood would have a few starts to "further audition as to where his situation may stand and/or may go to as we move forward."

Tulo, Helton removed after injuries flare up

MILWAUKEE -- Shortstop Troy Tulowitzki and first baseman Todd Helton were both removed in the middle of the Rockies' 2-1 loss to the Brewers on Tuesday night because their nagging injuries flared up during the contest.

Tulowitzki was removed midway through the sixth inning, and Helton was taken out in the eighth.

Manager Jim Tracy said Tulowitzki left the game with a sore left hip and Helton's back "tightened up a little bit."

"That's why they had to come out of the game, both of them," Tracy said, adding the veteran players were day to day. "We'll wait and see. We're kind of back and forth on it now."

Tulowitzki sat out Sunday's game against Cincinnati due to the sore hip. Helton had missed six of seven games before returning to the starting lineup Tuesday night.

Rookies playing in postseason atmosphere

MILWAUKEE -- The Rockies started mostly regulars against the Brewers on Tuesday night, but they did have rookies Jordan Pacheco and Wilin Rosario in the lineup, batting seventh and eighth, respectively.

Manager Jim Tracy said he wanted to get those players some experience playing in a pennant-race environment.

"This is another opportunity," Tracy said. "See what this is like. This is going to be a very, very noisy place. There's going to be a lot of people in here."

He said even though Drew Pomeranz and Alex White aren't pitching in the series in Milwaukee, the experience would help them also.

"It's really good for some of our young people, even those who aren't participating in the next couple days," Tracy said said.

Worth noting

Milwaukee manager Ron Roenicke saw a familiar face in the Rockies dugout. His nephew, right-hander Josh Roenicke, was claimed off waivers by Colorado in June after pitching previously for the Blue Jays.

Josh has a 2.19 ERA in 14 games.

"I saw Josh last year when he was with Toronto, and it's always difficult when there's family on the other side because you want him to do well," Roenicke said. "Your [own] team should come first, but it's fun seeing him. He's got a nice arm, and he's a tremendous athlete. Hopefully, we won't see him out there unless he's got a real big lead."
