For terms and presentation basics check out my Wainwright VEB post if you’re unsure of any of the language I use in the post.
Westbrook looks like he’ll fit in nicely with Papa Dunc. Here’s a chart showing fastball vertical movement compared to rv100
For this chart the more negative the rv100 the better, so the clear trend is that Westbrook’s fastball is better when he has more sink on it. Similarly here’s a vertical location chart
At the bottom of the zone is good for him, but he wont get many chases below the zone it looks like (high rv100 because of balls). Just a couple of things to watch for before tonight’s start.
