Thanks to the Marlins' 4-2 win over the Nationals in Game 1 of Sunday's doubleheader in D.C., the Cardinals will enter their series finale vs. the Brewers as a lock to make the playoffs.
But don't expect the National League Central leaders to make much of the clinched postseason spot. The Cardinals are locked in a tight pennant race, with the Pirates and Reds both in position to make a run for the division title in the final week.
In the other dugout, Brewers rookie Wily Peralta will try for consecutive wins for the first time since July 21. Peralta picked up his 10th victory on Monday, and while he didn't have his best stuff, he still limited the Cubs to one unearned run on five hits in six innings.
"[Peralta] scuffled off and on with his command, but made some really good pitches when he needed to," manager Ron Roenicke said after the game. "He still got us there, though. Still didn't give up many runs, and I think that's really important, when he doesn't have his best command that he can still keep us in the game, and he did."
Peralta worked out of a few jams to deliver a solid outing, something he might not have done earlier in his debut season.
"You may have seen a bit of [frustration] today, but it may last for a pitch and he gets back into it," Roenicke said. "We talk about progression and development of a player, you see what happens emotionally and are they able to regroup? I don't have any problem with a guy getting mad. It's how fast can you let go of it? I think Wily is getting better at that."
For the Cardinals, Joe Kelly will start as scheduled, though right calf tightness cut short his most recent outing . He threw a bullpen session on Thursday with no issues, and Kelly believes he will be fine for Sunday.
Brewers: Segura doubtful, Aramis likely for Sunday
All-star shortstop Jean Segura will likely miss his fourth straight game with a strained right hamstring Sunday. Roenicke said Segura is making progress, but isn't ready to return to action.
Roenicke did say Aramis Ramirez will be back in the lineup Sunday after a scheduled day off.
"Ramie's getting a day," Roenicke said before Saturday night's loss. "[We] have it mapped out a little bit going forward, what we're going to do. So he'll be back in tomorrow."
Cardinals: Closing duties to be handled by committee
With Edward Mujica out -- at least temporarily -- as the Cardinals' closer, the club will now approach the ninth by committee.
Though Mujica has 37 saves this year, he has blown three of his past five opportunities, and has allowed a run in six of his last 11 appearances, prompting the ninth-inning shift.
"A week away from October, you don't want to have to be rethinking your club all of a sudden. But sometimes you do," general manager John Mozeliak said. "You make adjustments or you go home. ... From our fan-base perspective, they just want to know if we're thinking about it. We are thinking about it, and we know we have to do something different."
• Matt Carpenter moved past Stan Musial to set the Cardinals' record for most doubles in a single season by a left-handed hitter with his 54th on Saturday night.
• Sunday is the last head-to-head matchup between Milwaukee and St. Louis this year. The Cardinals lead the season series, 14-4.
