First off, no, Zac Gallen's velocity wasn't the "lowest of his career". He was at 93.0 in 2019, 93.2 in 2020, and 93.4 in 2021. Last year's 93.5 is the exact same it was during his best season in 2023, when he was the 6th best SP. His velocity has been shockingly consistent, never deviating a full MPH from highest high to his lowest low. It's a bit on the below average side but velocity isn't king as much as you're acting. Velo can be nice, but velo does not equate K's or whiffs. We'll get a good look at that with Phil Maton who throws well below average for a RP and yet was in the 100th percentile in whiff rate.
Yes. My opinion on Imai's contract has not changed. He'll get $20+m aav. I do think it could be a sliding contract like Shota's, but it'll be a supersized version of it, like Zumach had the other day were 5/$100m could be a 3-year deal with an opt out or an 8-year deal type of a thing.
It won't be the closest. Kikuchi was slated to sign by January 2nd when he came over and signed on the 2nd.
