The Mets have reportedly signed RHP Alex Carrillo
He topped out at 101 in the Independent Frontier League, he has a low release and a hard slider
Here are numbers on him courtesy of @tony_baseball_ on X, the Mets may try getting him to throw a true FF instead of that sinker

New Met Justin Hagenman is a low-90's guy with 5 distinct pitch shapes
The changeup is the most intiruging pitch here with good depth and fade
This is another pitcher with upside the Mets will try out in spring training

When IVB can be misleading
I have been looking into arm angles as a way to try and quantify unexpected Movement
If a pitcher’s IVB is above what is average for their arm angles we might be able to infer it rides more than expected

Desi is highly respected in the pitching development world
Mets Director of Pitching Development, Eric Jagers, played and worked under Desi when he was the pitching coach at the University of Iowa
This is a big loss for the Yankees and a big gain for the Mets

Lance Brozdowski’s latest video got me thinking about the differences in team-wide fastballs shapes
So I plotted every four-seam fastball thrown by the #RedSox and #Cubs in 2024
Notice how the Cubs' fastballs have more cut, while the Red Sox have more true riding four-seamers
