Hogan Harris pt. 2

Last week: the return he'd get on a tick of velo, a platoon problem, and a workload gap.

This week: how we'd build his offseason, including the sweeper and cutter shapes we'd work towards, + more.

Seeing some big time emotion from the pitchers in game 1 of #WorldSeries in the 5th inning.

Starting to get fun already.

When training elite throwers the coach designs the environment. The environment should encourage movement exploration.

Favorite part of the offseason is movement exploration, and early on the job is building an environment the athlete can find his own solutions in.

massive implications on future of pitcher usage. Baseball is in such a cool state right now in this regard

in the past we had relievers in fireman roles, but then we got the closer, then we saw openers, some moderate length relievers...

This could be a gas next step

Most pitches thrown by a starter in a game where they are less than 3 days from their next outing

Sandy Alcantara (101 pitches)
Eury Perez (97 pitches)

Aaron Ashby (44 pitches)

What the Marlins are doing right now is groundbreaking, they are taking a starters normal mid-week bullpen and simply doing it in a game environment. I have so many questions about this....

- How different is the intent between the bullpen and the actual game? Can a starter effectively control their intent so as not to throw at 110% on just 3 days rest?
- Can this hold up over a large season sample?
- How does this affect them and the bullpen in terms of value (WAR, WPA)? How much value can a starter add by doing this for an additional ~30-50 innings in mid to high leverage outings?

Two things about Hogan Harris.

He'd get an unusually large return on a tick of velo

As a lefty he isn't getting the platoon edge his stuff should give him.

Both are fixable this offseason. 🧵
