Craig Kimbrel and Kenley Jansen are right where I'd expect.

Wade Miley was sprinting through his last start, he probably should have slowed down a bit. He sailed through 5 then 4 hits and a walk in the 6th. I really did think he was being unnecessarily (and not super effectively) quick, maybe especially for a guy fresh off the IL. Of course fresh off the IL, maybe he just ran out of gas in the normal way.

Is there any correlation of success vs tempo (in either direction )?

We've always heard you need to work faster to be successful but that list (on both ends) looks pretty random

It seems to me that if you had the ability to choose your tempo and still remain effective you'd do whatever annoyed individual batters the most, or at least whatever ticked off your own teammates the least. Rushing the ritual hitter types, and slowing way down when a guy is in the box early might affect some of them, but most are average and probably wouldn't be swayed too much. then I expect you'd just get moving to keep your infielders awake.

Yeah I'd be interested to see if there was any correlation. I think it would also be interesting to see if any pitchers vary by a meaningful amount and what that does. It always felt like Jon Lester got really slow when things weren't going well and it didn't help (where the cause/effect there is I don't know).

They're releasing this info now so that next year when they have the pitch clock they can show "transparently" how much things have improved.

Fangraphs used to publish Pace numbers in their pitch info/ plate discipline section, and then it disappeared a couple years ago... the column is blank. I'm sure they were told to pull it.

There is definitely correlation between MY annoyance at some of the slower pitchers and their Tempo

It seems to me that if you had the ability to choose your tempo and still remain effective you'd do whatever annoyed individual batters the most

I'm convinced that pitchers have figured that out, and actively do it, and in almost all cases that's to go slow, since the batter has to maintain his heightened state of readiness for longer, which becomes fatiguing. They go slow because it works better. If going faster worked better, they would have figured that out and be doing it.

Fun toy to play with - often confirms what I thought as a Jays fan - that Dolis was painfully slow for example (glad he is gone). That hitters influence on the speed is minimal vs the pitchers (spread is far smaller from hitter to hitter than pitcher to pitcher).
