ST. LOUIS (AP) — Andrew McCutchen homered and drove in three and the Milwaukee Brewers used eight pitchers in an 8-4 victory over the St. Louis Cardinals on Tuesday night.

The Brewers moved within seven games of the NL Central-leading Cardinals.

“We just take it day by day, at least I do,” McCutchen said. “You know, I don’t even know where we are right now in the standings.”

Down three starters to injuries, the taxed Brewers staff was stretched even further when starter Matt Bush left after just 15 pitches because of right groin discomfort. Bush was the starter in what the club had already designated as a bullpen game.

Brewers manager Craig Counsell said Bush is day-to-day.

Luis Perdomo (2-0) was the winner, allowing one run in three innings. Perdomo, Brad Boxberger, Hoby Milner, Justin Topa, Taylor Rogers and Brent Suter combined to retire 20 of 22 batters from the third inning on.

“I thought it started with Luis Perdomo for sure,” Counsell said. “His giving us three innings after really having to use two guys to get through the first was enormous and put the game back in order. Box’s inning was really important, I think just to get us kind of some matchups for the rest of the game. The guys just kind of took it from there. It was great effort.”MLBKershaw, Dodgers win another NL West title, blank D-backsMaton’s 7th-inning HR off Alcantara leads Phils past MarlinsWright earns 18th win, Braves beat Giants 5-1, gain on MetsYu Darvish dominates for 8 innings, Padres top Mariners 2-0

“Beating a really good team at their place with the bullpen game gives us a lot of confidence going forward, no doubt, but every day is a new day,” Suter said. “Next time we’re called upon to do that, we got to go out and execute. We can’t lose any steam or lose any focus.”

McCutchen hit his 17th homer of the season, a two-run blast off Jordan Montgomery in the fifth, to break a 4-all tie. Christian Yelich added to the lead by getting hit by Packy Naughton’s pitch with the bases loaded in the sixth.

“I thought it was a good pitch,” Montgomery said of the McCutchen homer. “He just put a good swing on it. Sometimes a good hitter puts a good swing on a good pitch.”

Hunter Renfroe had a pair of hits including an RBI single in the eighth.

Counsell was pleased with his hitters’ approach against Montgomery.

“He pitches in very very well and that’s what he’s that’s what he’s been really good at,” Counsell said. “It’s that fine line at swinging at that strike in that’s on the corner that’s tough to do anything with, and we pushed him out over the plate a little bit.”

The Brewers took a 2-0 lead in the first on RBI doubles from Willy Adames and McCutchen. Adames tied it with an RBI single in the second and Yelich drove in another on a fielder’s choice.

It was the worst start in eight tries as a Cardinal for Montgomery (8-4), who was acquired at the trade deadline from the New York Yankees. Montgomery allowed six runs, four earned, and gave up seven hits while striking out six.

“We did a really good job of being able to stay on him every inning and not really letting him give up a couple runs and kind of settle in,” McCutchen said. “We did a good job of just fighting back every inning and that put us in a good position for the rest of the game.”

Nolan Arenado had a two-run double in the first and Albert Pujols added an RBI single to give the Cardinals a short-lived 3-2 lead.

Tommy Edman’s RBI single in the second tied the game at 4-4. Edman has a career-high 14 game hitting streak.

“Each one of their guys, we know them really well,” Cardinals manager Oliver Marmol said of facing so many pitchers. “Our hitters meeting, we knew coming in this is what it would look like. We game planned for it. They beat us.”

UP NEXT

Cardinals RHP Adam Wainwright (10-9, 3.33 ERA) will start the second of a two-game series against the Brewers and RHP Corbin Burnes (10-6, 2.93 ERA). Wainwright and catcher Yadier Molina are expected to start game No. 325 together as batterymates, which would break the all-time record set by the Detroit Tigers duo Mickey Lolich and Bill Freehan (1963-1975). Burnes is 2-0 with a 0.43 ERA in three starts against St. Louis this season.
