Scouting report
It appears as though Goss has had a pretty significant spin rate spike. Both before the 2019 draft (data collection that occurred on the showcase circuit) and after, his fastball and the better of his two breaking balls spun at 2250 rpm and 2050 rpm, respectively. But as I called around to see if Rays stuff had changed based on 2020 data, Goss came up. His fastball now spins at a whopping 2600 rpm while his breaking balls are spinning closer to 2400. He's also throwing his fastball a little bit harder and his changeup now has much more velocity and rests in the upper-80s. Boots-on-the-ground scouts who saw instructs echoed the sentiments of the amateur arm of the industry from before Goss was drafted: he can really pitch. He was a low-90s (touching mid-90s) changeup/command high schooler whose breaking balls relied on Goss' deceptive slot to play, but his stuff has improved without detracting from his pitchability. Pro scouts now think the breaking ball has a chance to be plus. This is a 2021 breakout candidate. (Fall Instructional League)
