On the heels of a strong debut season for Red Bank Catholic, rising junior outfielder Dom Carabollo can now say he is a national champion.

Not only that, but Carabollo is the one who brought the national title home. He delivered a walk-off single in the bottom of the 11th inning to send his travel team, Tri-State Arsenal, to a win over the 6-4-3 DP Cougars of Marietta, Georgia, on Friday. The victory gave Tri-State Arsenal the 16U Perfect Game WWBA national title at the tournament at LakePoint Park South in Emerson, Georgia.
