My hunch (never right, however), is he starts season in "Hagersburg" and does second half at Potomac. Pitches his 160 innings recovery year. Then splits season at the real Harrisburg and Syracuse.
Is Ray, Solis, Cole are really good (plus Jordan and Karns?), no reason to rush Little Gio.
No chance he goes 160 next year.
I think he's more on the Cole/Ray plan.
Iirc, they opened their first full season in extended spring training, in part to limit their innings. With Giolitos ~40innings this year is the most in the past 2 years for him, so they'll be more cautious. 160 after TJ isn't the standard, at least not for a HS kid coming without any experience coming even close to that (maybe not even half, don't know his junior year totals off hand).
My guess is extended sprinf training to start, and about a 100 inning cap. Maybe he starts at Hagerstown, but still in the 100 inning territory imo. Any promotion to Potomac would take at least half the season imo, and won't impact the inning limit.
