What happened: The Los Angeles Dodgers are starting Miguel Rojas at third base to counter Atlanta Braves left-handed opener Ray Kerr. Dodgers manager Dave Roberts said the team plans to counter with left-handed hitter Max Muncy once right-hander Grant Holmes enters the game.

Why it matters: The lineup decision gives Los Angeles an early platoon advantage against Kerr in the postseason matchup. Holding Muncy on the bench preserves a favorable lefty-righty matchup for when the Braves deploy their primary bulk reliever.

What to watch: Watch how quickly Atlanta transitions from Kerr to Holmes, which will trigger the corresponding Dodgers substitution.
