The Ever-Expanding Postseason Bullpen
The flip side to the story of the Incredible Shrinking Postseason Starter — which, in fact, has only suffered more shrinkage since I published that piece about two weeks ago — is the expanded use of bullpens during this postseason. For the second year in a row, they’re throwing more than half of all innings this October, a situation that probably owes as much to the unique conditions of baseball in the time of the coronavirus pandemic as it does to analytically-inclined management.
Due to a combination of injuries and desperation, this past weekend’s three World Series games saw the six starters combine for just 17.2 innings, with only one lasting longer than four — and that one, Ian Anderson — was removed with a no-hitter in progress! Meanwhile, a total of 28 relievers came through the bullpen gates, an average of nearly five per team per game; they combined for 34.1 innings, nearly double the total of the starters but allowed just 10 runs to the shellshocked starters’ 24. Yes, the Braves’ use of the inexperienced Dylan Lee and Tucker Davidson to start Games 4 and 5 had something to do with it, but even Framber Valdez, the author of this postseason’s only eight-inning start, was chased after allowing five runs for the second straight turn. Valdez, in fact, has allowed 10 runs in this World Series, while the rest of his staffmates have yielded just eight.
Differentials like that, in which relievers have been much more effective than starters, help to explain what we’re seeing. While starting pitchers are often the stars who offer more name recognition to casual fans, given the urgency of October baseball there’s little sense in riding a starter who’s getting beaten up, regardless of the underlying reasons or the theoretical entertainment value. With the Astros carrying 13 pitchers on their 26-man World Series roster and the Braves 12, there are more than enough relievers to go around. Just one reliever pitched in Games 3, 4, and 5 — which is to say, made back-to-back appearances without a day off: the Astros’ Ryne Stanek, whose first appearance was just one batter and four pitches long. Only one other reliever in the entire postseason has pitched on three straight days, the Red Sox’s Martín Pérez. Read the rest of this entry »
