Yankees had a 8.47 ERA in the ALDS.

That's the worst ERA in any single postseason series in franchise history.

Pearls before swine. FOH with this garbage.
Is Judge just Mike Trout? Hopefully the mid career slump starts next year.

Aaron Judge hit .500 with a 1.273 OPS for the postseason (1.617 in thr AlLDS) and accounted for 2 of the Yankees’ 6 hits on the night they were eliminated. Rice, Wells, Grisham and Volpe had OPSes of .559 or lower vs. Toronto while the pitching staff posted an 8.47 ERA.

And that’s that for the Yankees. One night after a thrilling comeback from down five runs, they couldn’t muster a second one. The Blue Jays beat them 11 times in 17 games this season, and they move on to the ALCS to face the winner of Mariners/Tigers.

For the third night in a row, Volpe has struck out three times. The KKK took that baby away…

Since his double off Kevin Gausman in his second AB of Game 1, Anthony Volpe is 0-for-12 with 10 strikeouts.

Are there any baseball journos that travel with a jetboil french press and a hand grinder?

Back on my bullshit, by which I mean drinking terrible coffee before first pitch because I couldn’t score any greenies

new @fangraphs.com: a look at the contrast between the bullpens of the Yankees and Blue Jays last night, as the Yankees staved off elimination. Via colleage @mattmartell.fangraphs.com, some excellent insight from Gerrit Cole regarding the times-through-the-order and repeat-reliever effects.

People started using my Hall of Fame analysis system, which helped solidify a career change and allowed me to do a book. S’ok I guess

Aaron Judge on his home run last night, jokingly (after noting the wind):

“I guess a couple ghosts out there helped kind of keep that fair”

Judge’s home run was pushed 1 foot to the right by wind, creating a home run, per Statcast

Aaron Judge homering on this pitch is INSANE!

The PLV result likelihoods of this pitch:

Swinging Strike: 29.0%
Foul: 32.7%
In-Play Out: 13.0%

We aren't talking enough about how crazy this homerun was

The NCAA needs to fuck off ten thousand times over before boarding a rocket into the fucking sun, but it should really fuck off when it comes to this.

College athletes may be allowed to bet on pro sports soon 👀

The NCAA Division I Administrative Committee approved the recommendation Wednesday, but the new rules will only go into effect if Division II and Division III also approve.
