They've been recruiting for years now, in fact the higher caliber schools are likely finished recruiting position players at this point and are looking to add late blooming pitchers. There are over 100 freshmen that are committed to D1 programs already so the recruiting is happening - Vanderbilt has 20 commits for the class of 2021 right now.
Exit Velo is fairly irrelevant and 6.9 doesn't stand out as a D1 outfielder for top college coaches and especially pro scouts. At this point if you're asking when schools start recruiting - pro baseball is out of the equation and the question should be is he D1 material? I've never seen him play and the all tournament accolades are meaningless, but either his travel coaches don't think he's good enough to play in the upper half of D1 programs or they can't do a thing for him. Talk to his coach about potential schools he fits in at, if that goes nowhere time do find a new team. If he is as good as he's made out to be it should not be a problem finding a much stronger travel program.
