Sunday Notes: Marlins Prospect Thomas White Is Chasing an 80-Grade Sweeper
Thomas White is having an impressive first full professional season. Drafted 35th overall last year by the Miami Marlins out of Phillips Academy in Andover, Massachusetts, the 19-year-old left-hander has a 2.84 ERA, a 2.99 FIP, and a 29.6% strikeout rate over 76 innings between Low-A Jupiter and High-A Beloit. His late-May promotion to the higher of those two levels came for a simple reason. As our lead prospect analyst Eric Longenhagen explained when assigning him a 45+ in early June, White’s stuff was simply too good for the Florida State League.
I had an opportunity to talk to the promising youngster when Beloit played at West Michigan earlier this week, and one of the things I made it a point to learn about was the mindset that augments his arsenal. I began by asking him how much of a role analytics are playing in his development.
“I’m starting to learn more about the actual numbers and how all that stuff works,” White told me. “At the end of the day, I like to just go out and get outs — I’ve never been a big tech guy — but I definitely know a lot more about my pitches now that I have access to all the data. So, I’m still learning, and I want to learn, but the best measurement for me is how hitters react to them.”
The pitches that hitters are reacting to include a four-seam fastball that has been averaging, according to White, 95.6 mph and 17.5 inches of vertical ride. He is also throwing a two-seam changeup and a sweeper-slider. Currently in the works, but not yet part of his repertoire, is “a shorter gyro pitch,” either a cutter or a hard slider.
