The Brewers faced a different pitching staff in the postseason. Regular season featured one start by Yamamoto, one by Sheehan, 2 by Kershaw, and 2 by Glasnow. Zero by Ohtani. Glasnow's back-to-back starts against MKE in July were his first two after a three-month shoulder injury, so he wasn't as sharp or stretched out as he was in the playoffs. The relief corps the Dodgers used against Milwaukee during the regular season was Vesia, Trivino, Klein, Yates, Banda, Dreyer, Casparius, and Scott.
These were the postseason starters: Yamamoto, Ohtani, Snell, and Glasnow. Add in Sasaki out of the BP for three games. That's 31.1 of the 36 innings in the playoffs.
