The latest tool at Pitcher List is so absurdly sexy! Game-by-game instant analysis and analytics on every starting pitcher. We’re talking everything from velocity, iVB, usage, locations, SwStr%, and more!! This is a MUST FOLLOW if you’re a fantasy baseball fan and manager.

A bit of news on the Substack. Beginning March 8th, I will be moving back to paid subscriptions. This isn’t a decision I take lightly, but the amount of time and energy I put into this is overwhelming. I feel that the quality and volume of the work is at a level, I’m happy with.

Really, really liking what I’ve seen from Moreno over the last 8 months. IF (big if), he can stay healthy, he’s got the potential to be a borderline Top 10 catcher, especially if the power gains stick.

Players who have hit the ball harder than their career MaxEV in spring training so far:

1. Gabriel Moreno (ARI) 111.8mph (career max 111.1)
2. Ben Gamel (ATL) 111.4mph (career max 111.1)
3. Nick Senzel (LAD) 111.1mph (career max 109.8)
