Small point about the ball lodging at the bottom of the fence: fields are often sloped for water drainage. The bottom of the OF fence can be about a foot off from the level of home plate. Fences are usually lower, but in some places they're higher. Toronto, however, may be the flattest field in MLB.

I got stuck in a traffic jam the other day because a flock of turkeys were crossing a street against a red light. When I got home I googled "are turkeys colorblind" and found out that turkeys, in fact, have superior color vision to humans. So no excuse, turkeys are just inconsiderate jerks.

Given that it will be in the 40s in Toronto this weekend, the roof will probably be closed for games 6-7. So this is the last game with weather in the 2025 season. Already interesting!

On 9/11/2011, I woke up to a hole in my tire, very much like Aaron's hole today. It was part of a long series of strange coincidences, which I wrote about here:

ken.arneson.name/2011/09/a-ti...

Since I am no longer an A's fan, I pray that my karma of holes has not now been transferred onto Aaron.

Divisional Round | Yankee Stadium | Oct 7

Judge hooked one down the left-field line that clanged off the foul pole.

A 17 mph wind blowing out with a gentle push to the right kept it fair. A signature playoff moment with a little help from the 🌬️

Wild Card Round | Wrigley Field | Oct 1

Merrill hit a high 170 ft-apex fly ball into a 16 mph wind blowing in from right-center.

Suzuki drifted back, then adjusts to make a routine catch on a ball that was quietly the most wind-impacted play at Wrigley this series.

Top Weather Impacted Plays of the 2025 MLB #Postseason

As we count down to Game 1 of the #WorldSeries on Friday, we’re highlighting one play from each round of the playoffs that was most shaped by the weather.

First up: the Wild Card Round

Everytime I see Daulton Varsho, I always like to think other kids are named after their dad's teammates, and there may be a VanLandingham Manwaring or a Saltalamacchia Middlebrooks out there somewhere.

It helps that most of these games have been played under a roof or with winds under 5 mph. One of our findings @weatherapplied.com is that outfielders are positioned on average a foot closer to a fly ball’s eventual landing spot indoors vs outdoors.
It seems like every single outfielder this month is positioned perfectly. There’s no place to hit the ball.

The wind was only 12 mph at Wrigley, but most of the time, there's at least some kind of crosswind. For many fly balls a 12 mph wind might work like 6 mph in the direction of the ball. But that was straight into a pure 12 mph headwind headed from the right center gap directly at home plate.
Back on Aug. 20, Suzuki belted a 100+ mph fastball from Misiorowski to nearly the same right-center spot, but at Wrigley. And the wind blew that 22 feet back for a deep flyout, per Statcast (via @slangsonsports.bsky.social).

No wind here with the AmFam roof closed.

I flew to Seattle yesterday to replace some equipment at T-Mobile Park before this game. By the time this game is over, I’m going to have to fly to Seattle to perform an end-of-life replacement on the new equipment I installed yesterday.

I'm on data quality duty for @weatherapplied.com for tonight's game, but the roof is closed, so I theoretically shouldn't have much to do.

But I just got a scare because they just showed an old drone shot of an open roof on TV. At least I hope it was an old shot. Don't do that to me, Fox Sports.

Loved this. Patrick's last paragraph gets at something I've been poking at in my writing for over two decades now: sports analytics correlates everything with wins, or with money, or with money per win, but in the end, the actual purpose of sport is a set of human emotions.

Hello Seattle! I like your light rail from the airport to the stadiums, very convenient.

Even with the negative wind impact, this is the 2nd longest HR in MLB this season.

What was #1?

A 493 grand slam by A's rookie Nick Kurtz, aided by the wind adding 14 feet of distance.

My infrequent reminder: awards are celebrations, not measurements.

If you have two people worthy of celebration, and you already celebrated one of them last time, go ahead and celebrate the other person this time.

The Oakland Ballers radio announcer giving a "Holy Toledo" when they win the Pioneer League championship was a very nice touch.

We've had two wind-prevented-regular-home-run-but-instead-inside-the-park home runs in one season! The other was Patrick Bailey's walkoff on July 8 in San Francisco.
Daylen Lile’s inside-the-park home run was blown in 10 ft by wind, per Statcast, preventing an over-the-wall home run

But he still got the HR!

Here come the autumn winds…

Tuesday gave us the #1 MOST wind-impacted play of the 2025 MLB Season thus far!

On a windy day at Nationals Park, a 24 mph wind knocked Braves Ha-Seong Kim’s hit back a whopping 98 FEET from where it would have landed in calm conditions.
