DENVER -- In the wake of his team scoring one run in the last 16 innings, Brewers manager Ron Roenicke decided it was time to shake up his lineup.

Corey Hart hit in the leadoff position on Saturday, while Rickie Weeks moved to the No. 5 spot. Josh Wilson replaced Yuniesky Betancourt at shortstop and hit seventh.

"We just feel like we can't keep doing what we're doing," Roenicke said. "It's not really saying that anybody's not doing their job, but what it's doing is saying that we're trying to change things up enough to where it's a new look."

Weeks had never hit in the five-hole before Saturday's game, but he and the rest of the lineup were open to the change.

"We'll just shake things up, I guess," Weeks said. "Whether it's good or bad, I don't know. We've still got to play some good baseball."

Weeks said his approach wouldn't change now that he is hitting behind Prince Fielder, noting the only difference that he envisions is facing pitchers out of the stretch more often.

"I thought [Weeks] was doing a great job in the leadoff spot, but he's a guy that also drives in runs," Roenicke said. "Maybe putting him fifth gives him more of an opportunity to drive in runs." Hart had previously hit in the leadoff spot 83 times in his career, but not since July 22, 2009. The outfielder said he has been open to the switch for sometime, telling Roenicke "a couple weeks ago" that he'd be willing to bat first if the manager wanted to alter the lineup.

"The five-hole has been a tough spot for us all year," Hart said. "Guys hit in other spots and then get there, and for some reason it doesn't work out. Rickie's a logical choice.

"We're trying anything. This could be a good thing, and hopefully it works out."

Roenicke said that Hart's improved patience this season -- he has 27 walks in 65 games -- makes him an ideal candidate for the leadoff role.

"They're frustrated as much as we are with our lack of offense," Roenicke said of the team's hitters. "I think that anything that has a chance to change it and to wake you up and start anew, maybe that's a good thing to do."

K-Rod enjoys memorable Brewers debut

DENVER -- For all the hoopla surrounding the trade of Francisco Rodriguez to the Brewers, the team's fans had still not seen him throw a pitch as of the end of Friday night.

That all changed on Saturday, when Rodriguez tossed a scoreless eighth inning to earn the win in Milwaukee's comeback victory, 8-7, over the Rockies.

"That's what I was praying for," Rodriguez said. "Trying to keep the score tied and give the guy an opportunity to come up in the top of the ninth to swing the bat."

That guy was Rickie Weeks, whose ninth-inning homer off Rockies closer Huston Street made a winner out of Rodriguez. The right-hander allowed just one baserunner, and that came when Dexter Fowler reached on a Prince Fielder error.

"That's what I'm used to seeing from Frankie," Brewers manager Ron Roenicke said. "He's a competitor. He loves it when it's on the line."

Roenicke said that he planned to get Rodriguez, who hasn't pitched since July 8, into the game regardless of the situation. He chose to go with Rodriguez in the eighth and in the ninth handed the ball to John Axford, who responded by earning his 24th save of the season.

"Frankie was going to pitch tonight, he had to pitch today," Roenicke said. "Once we started getting him up, we never know what was going to happen there. But once we started getting him up, we were going to pitch him in [the eighth] inning."

Braun reflects on difficulty of hitting streak

DENVER -- Ryan Braun is a player that tends to make the game of baseball look easy, but a day after his 23-game hitting streak came to an end, he said keeping it alive was anything but.

"This is my fifth year in the Major Leagues, and I think my previous career best was also this year, and it was only 13 games," Braun said. "It's definitely not an easy thing to do. I think it's a cool thing to enjoy while you're going through it, and you recognize that it's extremely difficult and extremely challenging. You try to embrace it, because I don't know if I'll have the opportunity to do that again in my career."

The streak ended during the Brewers' 4-0 loss to the Rockies on Friday, when Braun went 0-for-3 with a strikeout and a pair of groundouts. He was on deck in the ninth when Colorado closer Huston Street struck out Nyjer Morgan to end the game.

Braun said that the streak -- the third-longest in team history behind Dave May's 24 in 1973 and Paul Molitor's 39 in '87 -- was certainly on his mind as he waited and hoped for one more at-bat.

"I think by the time you get to 10 or 12 games it's impossible not to think about it," Braun said. "It doesn't really change your approach. It's not like I ever go up to bat hoping that I don't get a hit, so it doesn't really change my mindset or anything. But I was definitely conscience of it by the time I got to 10 and 12 games."

Said manager Ron Roenicke: "He's been impressive all year. He's had three streaks this year, this one obviously long. He's been consistent all year. I think he's got the ability to hit differently than most guys do."
