We were at this game, we saw it all.

MILWAUKEE -- Bill Hall, of all people, walked four times and a pitcher delivered the most important hit of the game on the way to a Brewers win. Stranger things have surely happened, but not at Miller Park of late.

The usually free-swinging Hall drew four of the 11 walks issued by Astros pitchers, including a bases-loaded pass that scored the decisive run, and winning pitcher Dave Bush hit a key two-run single in the Brewers' balanced, 6-4 win at sold-out Miller Park on Saturday night.

Bush (9-9) pitched into the eighth inning for his third win in four starts, and he poked a bases-loaded hit just inside the first-base line to score a pair of runs and cap a four-run fourth inning that gave the Brewers the lead for good.

"He's been raking lately," Hall said with a smile. "I'm surprised they got him out. He's a great athlete, and he puts the ball in play a lot. Especially with the bases loaded, that's a big hit because it puts the opposing pitcher in a tough situation with the top of the lineup coming up again."

That opposing pitcher was Astros left-hander Wandy Rodriguez (9-7), who was called up earlier in the day to fill in for injured right-hander Roy Oswalt. Rodriguez issued all four of his walks in that inning, including a bases-loaded pass to David Bell that gave the Brewers a 2-1 lead.

Two batters later with two outs, Bush gave the Brewers some breathing room. He swung late on a 1-1 fastball from Rodriguez, but hit it past first baseman Mike Lamb to score a pair of runs. Had Bush -- a .184 hitter this year -- made an out, Rodriguez would have escaped having allowed just two runs.

"As a pitcher, I know the difference that can make," Bush said. "If you can escape it without giving up too many runs, it can give you a boost when you get back out there. I understand what kind of situation he was in, and I was glad I could come through there."

The 11 walks by Brewers hitters matched a season high, and five of those baserunners eventually scored. Hall also notched an RBI with a walk, from deposed Astros closer Brad Lidge in the sixth, for the Brewers' decisive fifth run.

"That's a bit of a sign that we're starting to come out of it a little bit," said Yost, whose offense has struggled since losing leadoff man Rickie Weeks to injury and cleanup hitter Carlos Lee in a trade.

Hall lined out leading off the second inning, then walked in his next four plate appearances, including an intentional pass in the eighth. His previous career high for walks in a game was three, accomplished just once -- July 23 of this season -- in Hall's five-year career.

"I called Billy into the office last night and talked to him about those situations," Yost said. "For me, Bill's a pretty good hitter right now, but he's got a chance to be a great hitter. The only thing that's holding him back is his discipline at the plate. You can't consistently swing at the pitcher's pitch. ... It's a fine line, because you have to be 'patiently aggressive' in the strike zone to be a really, really good hitter."

Hall, who is hitting .267 this season, leads the team with 27 home runs and 64 RBIs.

"I like to swing, but in order to be a hitter in the middle of the lineup, you've got to take your walks," Hall said. "You can't always do it yourself. There are other guys behind you who are going to pick you up and get hits, and that's what they did today."

Bush, meanwhile, did not walk a batter in seven-plus innings of work. He surrendered four runs on eight hits while striking out five and was the only Brewers hitter with more than one RBI in the game.

"That's a big hit, man," said Yost. "That's two RBIs, and we won the game by two runs. It's important that these guys continue to work on the offensive part of their game, because they have to be able to help themselves through bunting and getting a big hit every now and then."

Bush appeared headed for a complete game, working with a 5-2 lead and 80 pitches entering the eighth. But after Eric Munson homered on Bush's first pitch of the inning and pinch-hitter Orlando Palmeiro singled, the Brewers turned to a bullpen that had not surrendered a run in 17 consecutive innings.

"Aggravated is the best word for it," Bush said of his reaction to Munson's home run. "I still felt strong, but at that point in time, when the tying run comes up to the plate, we've got good guys in the bullpen."

The bullpen's scoreless streak remained intact, even when Taveras reached on a fielder's choice against Jose Capellan and scored on Lamb's single against closer Francisco Cordero. The run was charged to Bush because of the transference rule.

Cordero was called into overtime duty, according to Yost, because left-handed specialist Brian Shouse needed a day off. Cordero held Houston in check in the ninth for his ninth National League save in as many chances.
