          It's a four-game Saturday in the 2025 MLB division series!

          All eight remaining teams are in action -- and in the first game of the day, the Milwaukee Brewers rode a six-run first inning to a dominant win over the Chicago Cubs.

          Another pair of division rivalries face off after as the New York Yankees visit the Toronto Blue Jays. Then, Shohei Ohtani will head to the mound for the Los Angeles Dodgers against the Philadelphia Phillies in a highly anticipated NLDS showdown. And finally, the Seattle Mariners will host the Detroit Tigers in the nightcap of a loaded postseason day.

          We've got you covered with pregame lineups and postgame takeaways as each Day 1 matchup ends.

          The decision to start Matthew Boyd on three days' rest backfired on the Cubs so quickly that it's impossible not to point to that choice as the turning point in Game 1.

          Boyd wasn't sharp down the stretch of the regular season and after throwing 58 pitches on Tuesday, there were questions around if he could return to the mound so quickly and be effective. It was a head-scratching decision considering the team had a more-than-capable starter in Javier Assad ready to pitch after he was left off the wild-card roster. But Assad didn't make the NLDS roster either -- manager Craig Counsell called that a tough call -- making the whole situation a confusing one. The Cubs blew this game long before Boyd lasted just ⅔ of an inning in Saturday's opener. -- Jesse Rogers
