I don’t think many coaches or recruiters look at box scores of PG events. They are looking at non subjective metrics – Height, weight, fb velo, exit velo and infield velo. PG does a nice job of capturing that info without paying for the extra packages. Coaches and recruiters are looking for the tools they believe they can mold into what they want.
My son’s juco freshman season line was W-0, L-1, IP-12.1, ERA-6.57, H-9, R-9, BB-10, SO-19, and he touched 93 mph. First year of converting from a HS corner guy to pitcher, so the 93 got him some minor interest but nothing concrete. He came in the first week of his sophomore year hung a few 97’s in a scouted intra-squad game and signed a commitment to Razorbacks the next week. Arkansas didn’t care about last season’s results or how he’d do as a sophomore (he did well), being 6’ 5”, touching 97, and liking him during his visit was enough.
As for the b) kids that don’t belong at PG events, I think that’s BS. We initially went to PG events because my son enjoyed them. The last time he went was to specifically bump his fb metric as a HS senior. If your son wants to do a PG event then go for it, the great thing about baseball is that improbable happens all the time. Improbably, my son was rule 5’d by the Indians this season, stuck all year and pitched 63 innings in the MLB.
