There was a moment on Sunday when Randy Arozarena had just stolen second base in the eighth inning of a scoreless game. Wander Franco stood at the plate while Nelson Cruz waited in the on-deck circle; the Yankees hadn’t yet recorded an out. Meanwhile, 250 miles down I-95, the Nationals had just wrapped up a three-run fifth, pushing their lead over Boston to four runs. Making his major league debut, effectively wild youngster Joan Adon struck out Rafael Devers on perhaps his best breaking ball of the day. The Blue Jays were cruising. This was the moment when extra baseball felt most likely. Perhaps not All of the Extra Baseball, because of the Mariners’ deficit against the Angels, but some. Instead, to the annoyance of baseball hipsters everywhere, we’re left with a boring ol’ Yankees/Red Sox playoff game at Fenway Park featuring two Cy Young candidates.

This is only the second time the two franchises have met in the postseason since their heated, knuckleball-crushing, curse-breaking epic tilts of the early 2000s, with the other coming when Boston dispatched the Yankees 3-to-1 in the 2018 ALDS, a series that featured many of the same players we’ll see Tuesday, though not the ones directly involved in that series’ extracurricular activity. It feels like we see these teams play one another on national TV constantly (it’s convenient to haul equipment from Bristol, Connecticut to either Boston or New York), but they’ve only faced off six times in the last two-and-a-half months. The Yankees won all of those games, including the last two in dramatic fashion (not that that means anything). Our announced starters finished the season ranked one-two in American League pitcher WAR: Gerrit Cole is set to take the mound for New York, while Boston will start 11-year veteran Nathan Eovaldi. Here are your starting pitcher scouting reports:

After a wild Sunday afternoon that held plenty of drama for the final day of the regular season, the postseason field is set. Team Entropy ultimately found no joy, with the remaining playoff spots finally decided without the need for tiebreaker games. With the Wild Card round set to begin on Tuesday, here’s a look at the 10 teams in the playoffs and how they stack up against each other.

A quick refresher: my approach takes the three most important components of a team — their offense (wRC+), and their starting rotation and bullpen (50%/50% FIP- and RA9-) — and combines them to create an overall team quality metric. Since regular season records don’t matter in the playoffs, I’ve ranked the teams simply by their overall team quality, removing the factors for win percentage and expected win percentage.

The Dodgers and Giants spent the entire season battling each other for the NL West crown. Los Angeles won 50 games after the All-Star break to post the best record in the second half and only gained a single game on San Francisco. The closest the Dodgers were to overtaking the Giants was entering their series in San Francisco on September 3. Even though the division wasn’t actually decided until the final weekend, that series gave the Giants the edge they needed to secure their first division title since 2012. It’s a shame they’re lined up to face each other in a Division Series instead of the NLCS — should the Dodgers advance out of the Wild Card game, that is. Read the rest of this entry »

The playoffs feature the best teams, with the best hitters squaring off against the pitchers with the best stuff. The stakes and the quality of the competition force teams to respond to fluctuations in leverage more quickly than they would in the regular season. This response makes sense: every change in win probability has an outsized effect on championship probability, so major league clubs act accordingly.

In his dissection of Kevin Cash’s decision to pull Blake Snell in the sixth inning of Game Six of the 2020 World Series, Ben Lindbergh pointed out that starting pitchers leave playoff games earlier than regular season contests, with relief pitchers now throwing the majority of playoff innings. Lindbergh also noted that more playoff starters threw 3 1/3 innings or fewer in 2020 than went at least six, a product of teams’ acceptance of the third time through the order penalty. The third time through the order penalty is real, especially for starters who lack deep repertoires. Removing starters after they turn the lineup over once or twice in favor of a high-octane bullpen arm throwing 97 mph with a slider gives the pitching team a better chance of recording an out in situations where the outcome of the game hangs in the balance.

With starters aware that they are on a short leash and likely won’t see a hitter more than once or twice, I figured it was worth looking at how pitch usage changes in the postseason. I pulled every pitcher who threw at least 50 pitches in both the regular season and the playoffs from 2015-20. I calculated each pitcher’s pitch usage in the regular season and playoffs separately and took the differences in pitch usage for each pitch. My hypothesis was that hurlers who feature a bevy of different pitches would lean more on their more trusted offerings knowing they likely won’t be asked to go deep into the game and will be pulled at the first sign of any trouble. Similarly, I thought that pitchers who employ a limited arsenal would trust their favorite pitch with the increased pressure of getting their clubs back to the dugout without allowing runs.
