Somerville (N.J.) Immaculata center Mark Brazinski made his decision on Sunday night at the UnderArmour All-America Game in Orlando.
Brazinski picked the Cal hat, giving the Golden Bears his commitment.
"I have come to the conclusion that the university for me is, California," said Brazinski.
Brazinski chose Cal over Penn, North Carolina, Boston College and Florida State.
Scout will have more with Brazinski following the game.
