St. Bonaventure beats UCLA in play-in game.

The basketball was still high in the air — flung to start the celebration — when the buzzer sounded and the Bonnies’ longawaited March celebration commenced. Players chest-bumped. Coach Mark Schmidt jumped and waved his arms.

The crowd at the University of Dayton Arena in Ohio — a place where St. Bonaventure is usually booed — got caught up in the moment, too.

Courtney Stockard returned from a hamstring injury and scored 26 points, and Jaylen Adams hit a jumper and three free throws in the final minute Tuesday night, rallying the Bonnies to a 65-58 victory over UCLA and their first NCAA Tournament victory since 1970.

“It can’t get better,” Schmidt said.

They’ll have more chances. The 11th-seeded Bonnies (26-7) will play sixth-seeded Florida in Dallas on Thursday in the East Region.

“Florida’s got four or five days on us, so we’ll be watching tape on the plane,” Schmidt said.

UCLA (21-12) was surprised that it was relegated to the First Four for the first time — the Bruins have been to 18 Final Fours. They had trouble making shots against the Bonnies’ zone defense and matched their season high with 20 turnovers.

UCLA’s Aaron Holiday led the Pac-12 in scoring but couldn’t put his touch on the First Four game. He scored 20 points but had 10 turnovers, including three in the final 29 seconds as the game slipped away.

“I felt like we matched them pretty well,” Holiday said. “We just turned the ball over too much.”
