Hi. Welcome.
I am going to be straightforward -
6''2" 180 lb RHP with a 3.98 uwGPA / 4.25 wGPA and playing multiple sports and being a nice, hardworking, coachable guy are all strong attributes.
But throwing low 80s unless he's a low slot/submariner means he is probably not going to pitch in college, def not D1. And a 7.0 60 is not enough either. HS stats don't mean much since the level of play and competition varies greatly.
Great idea to attend Showball and PTW and get updated metrics from a neutral third party....really hope he has a big jump in velo and running speed.
But unless something pops soon, you need to go into selling mode and open up your lens as far as schools if he wants to play college ball. The competition for slots at HA D1s and D3s is intense. Based on the metrics you've provided your son is a marginal D3 player, at best.*
An advocate - a club or HS coach typically - who can field interest and make calls on his behalf will greatly help.
Open up your lens. Be open to any and all feedback you get from Showball and PTW, even if that feedback is silence.

Someone posted this a while ago and I think it's still accurate. Thought it might help.
Tier 1: MIT/Cal Tech. freakishly hard to get in. Need 3.9+ uwGPA, impressive extracirriculars, 1520+/35+. Even if you are a stud player... total crap shoot. Mandatory test scores.
Tier2A: Johns Hopkins/UnivChicago. 3.9+ uwGPA. 1500+/34-35+. Mandatory test scores.
Tier2B: Swarthmore/Williams/Pomona /Tufts/WUSTL/Emory/CMS/W&L/Amherst/Bowdoin/Middlebury/Colby/Haverford/Babson: 3.8-3.9 uwGPA, Still definitely will want test scores. Maybe as low as 1400+ can possibly do it if you have mad skills or even lower if you have under represented minority status.
Tier 3: NYU/CWRU/Hamilton/Brandeis/Rochester/Wesleyan/Grinnell/Trinity (CT)/WPI/RPI/Stevens/Bates/Carleton/Macalester/Wesleyan: 3.75 + uwGPA, Still generally will want test scores. Maybe 1300+ can do it?
Tier 4: DePauw/Denison/Gettysburg/Washington and Jeff/Trinity TX/Franklin Marshall/Kenyon/Occidental/Wooster/Chapman/Whittier/Centre/Clark/Wheaton/Lewis and Clark/Dickenson/Muhlenberg/Whitman/rose hulman)/a few others. Now we're getting to schools that might be test optional.
* My daughter dated a baseball pitcher at her HA D3...he was 6'5" and threw 93mph at the end of his freshman year. In D3.
It's rough out there.
