The rest of your key stats are subject to many variables i.e., quality of competition faced, level of play, quality of own team, umpiring competency, official scoring vagaries, etc. etc.
Which are the same variables that will be faced at the college level. Heck you could even say the same variables faced in MLB.
Edit: I've just been to the TMP site, this looks like single position skills "showcase". Sorry I was under the impression it was a college exposure skills tournament.
