English broke a tie with a 3-pointer with 32 seconds left but Emmy Andujar made two free throws after he was fouled on a putback attempt to make it a one-point game. Laury was fouled before the inbounds pass and hit the clutch free throws.
Manhattan called a timeout at 4.9 seconds but Zane Waterman's long, contest 3 from the left wing wasn't close.
