Second-seeded Ohio State and seventh-seeded Gonzaga were tied at 61 with 4:03 remaining. The Sweet Sixteen awaited the winner. The difference in the end: Ohio State's defense, said coach Thad Matta. Gonzaga went 0-for-5 shooting from there and finished by making one of its last seven. “We had guys helping each other down the stretch,” Matta said. “A great job of challenging.”
