MIAMI -- Manny Parra was surprised when he arrived at the ballpark on Thursday and was told that he would start Sunday in St. Louis. Dave Bush was even more surprised to learn that he would not.

Bush has been getting treatment for a blister on his right middle finger since May 27, but he pitched a quality start against the Marlins on Tuesday and said that ailment was not a factor in the team's decision to skip his turn in favor of Parra. Bush was informed of the change by Brewers manager Ken Macha and pitching coach Rick Peterson.

"The blister has absolutely nothing to do with it. I don't know what the rationale is," Bush said. "They didn't even ask about my blister. It didn't come up, it's not an issue and it didn't affect me the other day. I don't really know what's going on."

Macha said "it is highly likely" that Bush will pitch in the subsequent series against the Cubs at Miller Park. Club officials will meet after the Cardinals series to make some decisions.

"We have to see how these guys perform," Macha said. "Right now, we have the second-highest ERA in the National League and we're looking for somebody. If you want to step up, step up and claim a spot."

Some might say that Bush did just that on Tuesday, when he fell into a 3-0 hole in the first inning but allowed no more runs through the sixth, when the blister cut his night short.

"We're not picking on Bush, OK?" Macha said. "We've not given Manny a fair shake. We asked him to come in in relief in the extra-inning game at Minnesota [on May 22] and that eliminated the start he was going to get the next day. So this is how this thing fit. We're not picking on Bush at all. Nobody has said he's out of the rotation or in the bullpen. He will be there for a couple days and we'll see how the things fit after Sunday."

The Brewers will start a left-hander in all three games against the Cardinals, who entered Thursday batting .243 with a .674 OPS against left-handed pitchers and .272 with a .782 OPS against righties.

Bush is 2-6 with a 6.45 ERA in nine career starts against St. Louis including 0-3 with a 10.57 ERA at Busch Stadium. Compare that to Parra, who is 2-1 with a 2.97 ERA in 12 games, including 10 starts, against the Cardinals and is 2-0 with a 2.86 ERA in five starts at Busch Stadium.

In his two starts this season, Parra has lasted only seven total innings.

"I'm excited any time I get to start," Parra said. "But other than the fact I'm going to start Sunday, I know absolutely nothing. It really doesn't matter, because there's no reason for me to think about anything else."

Bush was asked whether he was upset.

"I don't get upset a lot, so I would say no," he said. "But I don't have any idea what's going on. It was sort of vague as an explanation, so I'm hanging in limbo right now other than knowing I won't be pitching Sunday."

Macha: No instant replay

MIAMI -- By Thursday, Brewers manager Ken Macha had seen the blown call in Detroit that cost Tigers right-hander Armando Galarraga a perfect game. But it didn't change Macha's opinion on instant replay in baseball one bit.

"I'm against it," Macha said. "Let me throw this one out there: What if the guy was safe and they called him out? What if he had two strikes on the hitter and threw one right down the middle and the guy called it a ball, and the next pitch, he walked him? You're getting into so many hypotheticals.

"The guy missed a call, and he's admitted it. That's part of the game. So I'm totally against [replay]. I don't know what they are going to do."

Commissioner Bud Selig said on Thursday said that he will review Major League Baseball's umpiring system and the possibility of expanding the use of instant replay.

"Let me tell you what, there have been some great plays in baseball where the guy missed the call," Macha said. "They've got Jackie Robinson stealing home and Yogi Berra back there. [Robinson] is out! And they called him safe. Go look at the replay. How many times have they put that out there?"

Macha also mentioned an iconic play from the 2001 American League Division Series, when Yankees shortstop Derek Jeter ranged into foul ground to recover a missed cutoff throw and flipped the ball home in time, at least according to the call, to retire Jeremy Giambi.

"I was there. Slow it down, he's safe!" Macha said.

That play helped the Yankees end Oakland's '01 season. Still, Macha is no fan of expanded use of replay. "This is a human game, played by humans and officiated by humans," he said.

Gamel replaces waiver claim Heether

MIAMI -- Longtime Brewers farmhand Adam Heether, fresh off a two-homer game, was claimed off waivers Thursday by the Oakland A's and replaced at Triple-A Nashville by rehabbing third-base prospect Mat Gamel.

Gamel is still in the midst of a 20-game rehabilitation assignment as he recovers from a torn muscle in his upper back, behind his right shoulder, that he suffered in Spring Training. He batted .393 in eight games for Double-A Huntsville with a home run and five RBIs before Thursday's promotion.

Heether's two homers in Triple-A Nashville's win over Albuquerque on Wednesday night gave him nine this season, three more than any other Milwaukee farmhand. He is hitting .245 this season with 28 RBIs.

The Brewers also formally announced the signing of reliever Brian Bruney, released by the Nationals last month, to a Minor League contract. The Brewers assigned Bruney to the Helena roster but that's a formality while he goes to extended spring camp to get back to pitching shape. Bruney will report to Nashville before long.

And, as expected, former first-round Draft pick Mark Rogers was transferred back to Double-A Huntsville after making one start for Nashville on Wednesday night. Rogers helped the Sounds bridge the gap to right-hander Marco Estrada's return to the Triple-A rotation.

Also, outfielder Adam Stern, designated for assignment on Monday, cleared waivers and accepted an outright assignment to Triple-A Nashville.

Fielder: Griffey retirement 'best thing'

MIAMI -- Brewers slugger Prince Fielder grew up playing video games featuring Ken Griffey Jr. and counts Griffey as a great friend. He wishes his friend well in retirement.

Griffey announced Wednesday that he was retiring after 22 seasons.

"Everybody knows that was my guy growing up, more so as a friend than as a fan," Fielder said. "It's unfortunate for the game of baseball, but it's his decision. He'll be fine [financially], and he's got kids. He has a nice house down the street from me. I think this was the best thing. He was able to finish in Seattle, so it's good."

Does Fielder have an idea what Griffey will do in retirement?

"Golf and chill with his sons," Fielder said.

Brewers outfielder Jim Edmonds, an American League West foe of Griffey's from 1993-99, when Edmonds was in Anaheim and Griffey was in Seattle, said he was "totally shocked" by news of Griffey's retirement.

"He's one of the best ever," Edmonds said. "He's the best all-around player I've ever seen in my era."

Of Griffey's somewhat awkward exit, Edmonds said: "They're always going to be like that when you're that good. I figure that things weren't going the way he wanted to and he decided it was time. But 22 years, it's amazing."
