Short Work: A Look at This Year’s Postseason Starting Pitching

Jonathan Dyer and Kirby Lee-Imagn Images The American League Championship Series between the Rays and Guardians was a study in contrasts when it came to starting pitching, particularly as the series extended. Tampa Bay’s starters lasted five or more innings in all but one of the six games, with Drew Rasmussen and Freddy Peralta combining for three starts of at least six innings; the former went seven innings and the latter 5 1/3 in the the final two games. Cleveland’s starters reached the five-inning mark just twice and never went deeper than that; over the final three games, the team’s starters — ace Parker Messick and reliever Shawn Armstrong, who was deputized to open Games 4 and 6 — totaled just four innings. Given that imbalance, it was hardly a surprise that the Rays rallied from a 2-1 deficit to win those three and take the series. The World Series might present a similar contrast. The Rays and the Yankees are the only teams whose starters have averaged at least five innings per turn during this postseason, and Tampa Bay knocked off New York in a Division Series sweep earlier this month. Meanwhile, the Brewers are one of five teams whose starters have averaged less than four innings per turn; only twice did a Milwaukee starter even last five innings, with Logan Henderson reaching that mark in Game 2 of the NLDS against the Padres and Robert Gasser doing so in Game 3 of the NLCS against the Dodgers. Jacob Misiorowski — the likely NL Cy Young winner, who even before the playoffs had already exceeded his total workload from last year by more than 30 innings — burned through 88 pitches to complete four innings in his NLDS start and 94 to go 4 1/3 in his NLCS start. For the Brewers and Rays, those divergent approaches have worked. Tampa Bay went a combined 7-2 in the ALDS and ALCS; Milwaukee, 7-1 in the NLDS and NLCS. After a season in which he ranked third in the AL in FIP (2.81) and WAR (5.0) and fourth in ERA (2.67), Rasmussen began his postseason by no-hitting the Yankees for 7 2/3 innings in the Division Series opener. In three starts totaling 21 innings, he’s delivered a 1.29 ERA and a 2.58 FIP. Peralta, who struggled during his four months as a Met before righting himself somewhat as a Ray following a deadline deal, has put up a 1.13 ERA and a 3.72 FIP in 16 innings as a starter, on top of which he added two-thirds of an inning out of the bullpen in ALCS Game 4; that cherry on top of his two strong starts helped him win series MVP honors. While their third and fourth starters, Nick Martinez and Griffin Jax, haven’t been as effective, the Rays’ postseason rotation ERA is good enough to crack the top 10 dating back to the start of division play in 1969:FanGraphs Playoff Coverage Is for MembersYou must be a Member in order to read our postseason coverage.
