Some personal news.
After embarking on a side quest for the past 2+ years with an early stage startup, I'm excited to share that I'm joining the Boston Red Sox R&D group as a Sr. Backend Engineer.
I always knew I was going to return to baseball--it's humbling to be a part of such a historic org.

Yep was surprised Oracle's deepest point wasn't in the top three, suspected Colorado was going to be the deepest--and who can forget Tal's Hill?

Surprised to see Oracle as 5th deepest. Good stuff here.

All ballparks started using humidors starting in the 2022 season, I know in the '21 derby it was mentioned publicly that the humidor was not used for the Coors ASG HR Derby. I wonder if that's the case here as well, maybe minimal impact, but storage conditions were the first thing that came to mind.

Oneil a close second.

I totally forgot that I'd said this months ago but I'm glad I did after looking at Acuรฑa's 433 ft homer last night

I always think of the 1927-28 Tigers logo when this topic comes up, but it's so ridiculous that it now holds a special place in my heart. Looks like a cereal box.

Statcast Park Factors
Baseball Savant
BTW, I would love to hear any insight and input you have on the Sutter Health ballpark environment--there is probably not enough data yet but early returns is that it has among the highest park factors right up there with Coors (obviously very different). baseballsavant.mlb.com/leaderboard/...

Also given that the A's would regularly play in a park that was consistently the coolest in all of MLB (where I grew up originally) that temperature was closer to the 60's at night in the summertime, so close to ten feet is non-negligible.

We're just being flippant, as someone who went to school and lived in Davis area during the summertime--it's fun to point out that the park is going to be a hot wasteland.

Didn't see this anywhere but...it took Xavier Edwards 320 plate appearances before he logged his first barrel for the 2025 season which happened today on a flyout (HR in 13 parks).

๐จNew Statcast release day at Baseball Savant from the gang
This time: Catcher stance data. Which of your favorite catchers are using one knee down? (All of them.) Is the impact bad? (No.)
The trend here is overwhelming.

Looks like it's some kind of interdependency between Google Cloud and CF. CF operates a global edge network of data centers, but a lot of GCP services sit in front of CF, so this indeed may be mostly caused by a major GCP outage...guess we'll find out.

Apparently itโs some network configuration error involving Cloudflare from what Iโve been able to piece together but might be something deeper than that similar to a physical backbone (like L3, etc.) โ sure weโll get the full post mortem.

Today is a humble reminder that most major internet services and infrastructure in 2025 are not the decentralized networks that were dreamed up by the government over half a century ago. Cloudflare probably handles way too much of our DNS and CDN, we trade scaled convenience in favor of resiliency.
