Why have the Dodgers shortened their bench in the playoffs?

Through their first seven postseason games, the Dodgers have given at-bats to three position players off their bench: Nick Punto, Skip Schumaker and Michael Young — no Tim Federowicz, Scott Van Slyke or Dee Gordon.

Why the short bench?

“It depends on how the game goes,” Dodgers manager Don Mattingly said. “These games have been telling us what to do. When your starting pitching is going deep every day, you don’t use pinch-hitters. Zack went 8, right? Kersh was 7 full. Ryu — when guys are going deep you don’t use pinch-hitters.”

The script changed on Tuesday. Dodgers starter Ricky Nolasco was removed after four innings. Schumaker pinch-hit for the pitcher’s spot, then was removed from the game, so we could see more of the Dodgers’ bench tonight.
