Milwaukee Brewers outfielder Isaac Collins will move into the starting lineup for the first time this postseason. Collins came off the bench twice during the NLDS versus the Chicago Cubs. He'll now enter the lineup for the first time as he'll bat eighth and start in left field against left-hander Blake Snell. Collins slashed .263/.368/.411 with nine home runs, 54 RBI, and 16 stolen bases in 130 games during the regular season. On Monday, Sal Frelick will move over to center field while Blake Perkins heads to the bench.

Milwaukee Brewers pitcher Aaron Ashby will serve as the opener for Game 1 of the NLCS versus the Los Angeles Dodgers. Ashby served as the opener for Game 2 of the NLDS against the Chicago Cubs. He gave up three runs in 1.2 innings, but he has been a viable option for the Brewers outside of that. The southpaw posted a 2.16 ERA, 1.17 WHIP, and a 76/24 K/BB ratio across 43 appearances with the Brewers in the regular season. The assumption is that the Brewers are using Ashby to face Shohei Ohtani and Freddie Freeman. Quinn Priester figures to pitch a bulk of the innings during Monday's game.

Milwaukee Brewers outfielder Jackson Chourio will move into the leadoff spot in the lineup ahead of Game 1 of the NLCS versus the Los Angeles Dodgers. Chourio appears to be back at full strength after suffering a hamstring injury during Game 1 of the NLDS. Despite the injury, Chourio was able to go 7-for-19 at the plate with one home run and six RBI during the five-game series versus the Chicago Cubs. Sometimes, Christian Yelich takes over in the leadoff spot, but the Brewers will opt to go with Chourio against left-hander Blake Snell. The 21-year-old figures to be an important factor for this series.

Toronto Blue Jays outfielder Anthony Santander (back) has been scratched from Game 2 of the American League Championship Series on Monday against the visiting Seattle Mariners due to lower-back tightness, according to Shi Davidi of Sportsnet. In his place, Davis Schneider will start in left field and bat eighth in the order versus Mariners right-hander Logan Gilbert. Santander played in only 54 regular-season games due to injury in his first year in Toronto, but he was able to return in the final month and has gone 3-for-13 with two RBI and four strikeouts in the team's four playoff games so far this October. It's unclear if Santander's back injury will keep him out beyond Game 2 of the ALCS, but the good news is he'll have a day off on Tuesday before the series continues for Game 3 in Seattle on Wednesday. Schneider has never faced Gilbert in his career.
