I used the bottom up vs top down method of access to NECBL.
While on vacation (timed around the league schedule) , dropped the HS'er off at the field and had johnny introduce himself to the players and coaches (3 hours before game time of course) as a potential volunteer. ("Whatever you need fellas.")
2 yaers later, he contacted the coach and was given a roster spot. He ultimately went to the Northwoods (Top Down meithod), but the bottom up method worked for him.
Note: Bring ID, HS Transcript, SS Card< Baseball details, HS Coach contact, etc. (Just ib case). The team accepted him
HS players can potentially get a leg up on NECBL: Teams by reaching out for opportunites during the season. As much as you are attempting to sway college recruiters, you can sway Summer League Coaches
They need to know who you are. Referrals from College Coaches is the norm, but not the only means of securing a roster spot.
Volunteer for home game ballboy (ballperson) or bull pen assistant (for pitchers).
This shows a real interest in the program and provides early interaction with the coaching staff/managers as well as intel from college players (priceless).
