Peralta took the loss to the Cubs on Thursday in Game 4 of the National League Division Series. He allowed three runs on three hits and two walks while striking out six over four innings.

Ian Happ did all of the damage against Peralta with one swing of the bat in the first inning. Peralta threw 55 of his 84 pitches for strikes, generating 15 swings-and-misses in total. He hasn't quite performed up to his usual standards this postseason (4.66 ERA), and the Brewers are now looking at another bullpen game in Saturday's decisive Game 5 after getting out to a 2-0 series lead initially.

Boyd did not factor into the decision in Thursday's win over the Brewers in Game 4 of the National League Division Series. He allowed two hits and three walks while striking out six over 4.2 scoreless innings.

The lefty changed speeds effectively and left the mound to a standing ovation from the Wrigley Field faithful, having fanned Christian Yelich with two runners in scoring position for his final out. Boyd has posted a 2.79 ERA and 1.55 WHIP in 9.2 innings spanning three starts this postseason after putting up a 3.21 ERA and 1.09 WHIP across 31 starts (179.2 innings) during the regular season.

Castellanos went 1-for-4 with a double and an RBI in Game 4 of the NLDS against the Dodgers on Thursday.

Castellanos started each of the final three games and went 2-for-15 with five strikeouts in the series. Despite the poor overall numbers, he delivered a key knock in Thursday's loss by doubling in the seventh inning to give the Phillies a lead. Castellanos is entering the final year of his current contract, but he could be a trade candidate or otherwise have a change of scenery this offseason after managing only a 90 wRC+ across 589 plate appearances in 2025.

Happ went 1-for-5 with a three-run home run in Thursday's 6-0 win over the Brewers in Game 4 of the National League Division Series.

After Nico Hoerner and Kyle Tucker reached base in the bottom of the first inning, Happ cashed in with a three-run homer, which proved to be enough offense to win the game and even the series. The homer was Happ's second of the playoffs, though he's struggled overall with a .115 average (3-for-26) and 11 strikeouts this postseason.

Bader (groin) went 0-for-1 with a strikeout in Game 4 of the NLDS on Thursday against the Dodgers.

Bader was out of the lineup due to a groin injury but appeared as a pinch hitter in the 11th inning. He was immediately replaced for defensive purposes, suggesting he may not have been feeling healthy enough to handle left field. Bader could be headed for recovery early in the offseason, but he should be healthy in plenty of time for spring training.

Sanchez allowed one earned run on five hits and one walk while striking out five across 6.1 innings in Game 4 of the NLDS against the Dodgers on Thursday. He did not factor into the decision.

Sanchez was in a compelling pitcher's duel with Tyler Glasnow, with his only run coming on an inherited runner after he exited the game. While Sanchez didn't overpower the Dodgers' lineup, he induced 10 groundouts to go along with 14 swinging strikes on 95 total pitches. Despite it coming in a losing effort, Sanchez wrapped up an excellent 2025 season and is very likely to be a Cy Young finalist in the coming weeks.

Betts went 1-for-4 with an RBI and a walk in Game 4 of the NLDS against the Phillies on Thursday.

The matchup was a pitcher's duel between Cristopher Sanchez and Tyler Glasnow, and Betts had one of the most important at-bats of the low-scoring affair. He came to the plate with the bases loaded and two outs in the seventh inning, when he worked a walk to tie the game at 1-1. While Betts had a subpar regular season relative to his lofty standards, he's gone 10-for-26 with four RBI across six postseason contests.

Glasnow allowed two hits and three walks while striking out eight across six scoreless innings Thursday in Game 4 of the NLDS against the Phillies. He did not factor into the decision.

Glasnow made a relief appearance in Game 1 of the series, contributing 1.2 scoreless innings in a Dodgers' win. He was excellent in the decisive game Thursday, generating 16 swinging strikes on only 83 total pitches while also not allowing a hit from the second through fifth inning. Manager Dave Roberts said he removed Glasnow due to cramping per Dylan Hernandez of the Los Angeles Times, though it doesn't look likely to affect his status for the NLCS.

Wrobleski was added to the Dodgers' roster for the NLDS on Thursday.

The 25-year-old lefty will serve as an injury replacement for Tanner Scott (lower body). Wrobleski finished the regular season with a 4.32 ERA and 1.23 WHIP across 66.2 innings in the majors, so he likely won't see many high-leverage opportunities in the postseason.

Garrett underwent UCL reconstruction on his right elbow Wednesday, Jorge Castillo of ESPN.com reports.

Garrett had hope to avoid UCL surgery and treat the injury with a platelet-rich plasma injection, but ultimately it was decided a reconstruction was the best course of action. The righty previously had an operation to move a nerve in his elbow, so he'll be recovering from dual surgeries on his pitching arm. Garrett will not be ready to pitch again until the 2027 season.
