An Angels fansite report when he later got to their 60 this summer cites a curve as the Junior year difference maker.
Their source for that this campus story https://247sports.com/college/tennessee/Article/Tennessee-Vols-Baseball-Vols-Garrett-Stallings-selected-in-fifth-round-of-MLB-Draft-132589216/ also has the details he was their 2019 Friday night guy even with Crochet on the team.
His Perfect Game blurb from high school times mentioned three-quarters to over the top arm angle, gee whiz.
Who knows if he could have had Kevin Smith's 2019 in parallel universe 2020? SEC trade imports links them, but Smith actually doing it including a little AA success is a big credit in his favor for the moment.
He fits the Smith/Kjerstad mold of SEC guys steadily improving (Growth Mindset?), even if some of that is demonstrated in small sample sizes. Smith did backup his Junior Year rise up draft boards with his great 2019 for the Mets. I am imagining entering Junior year Stallings was not a 5th or 25th round profile. He's one more piece for the box of chocolates we'll get to open in the spring.
I'd learned he was a Josh Towers/Josh Tomlin strike-thrower type from the FG story, but was taken aback by how few strikeouts his Freshman/Sophomore year - that's some Ballard stuff.
He made quite a leap Junior year, and was also co-Garrett on the Volunteers with Garrett Crochet. Our guy beat the White Sox guy by about a run of ERA both years they were teammates.
If you are Elias, would you dangle Severino to the Rockies? They non tendered the “beloved by everyone who watches baseball” Tony Wolters, who was their starter. They have 2 catchers in the 40 and Sevy would be an immediate upgrade to both.
His offense would probably get a big boost in Colorado and he shouldn’t have to worry about defense much, since pitches don’t break anyway there.
I don’t know anything about the Rockies system, so not sure what a decent pick up would be.
