Managerial Report Cards: National League Division Series

Ah yes, the postseason. As Jay Jaffe noted yesterday, it’s nothing like the regular season. Here, managers have to grind out every edge possible. Continuing a series that I started last year, I’ll be assigning managerial grades for each vanquished team. They’ll cover on-field managerial decisions: chiefly, lineup construction, pinch hitting, and pitcher usage.
My goal is to rank each manager in terms of process, not results. If you bring in your best pitcher to face their best hitter in a huge spot, that’s a good decision regardless of outcome. Try a triple steal with the bases loaded only to have the other team make four throwing errors to score three runs? I’m probably going to call that a blunder even though it worked out. Managers do plenty of other things – getting team buy-in for new strategies and unconventional bullpen usage behind closed doors is one I find particularly valuable – but as I have no insight into how that’s accomplished or how each manager differs, I can’t exactly assign grades for that.
Another thing I’m trying to avoid? Relying too much on “leaning on your trusted veterans.” That’s never really been a strategy I love without knowing the underlying data, but mentioning it lets me drop this delightful statistic: “proven veterans” Justin Verlander, Max Scherzer, and Charlie Morton each have a 13.50 ERA this postseason. That’s not in aggregate; each of them has that exact mark. The playoffs are about overpowering your opponent in big spots. Which pitchers and hitters teams use to do so is entirely up to them, but if the justification for a move is “but he’s a veteran,” I’m going to judge that decision harshly. Let’s get to it.
