New York — Grant Mullins scored 20 points and Columbia rallied to beat UC Irvine 73-67 on Tuesday night to win the CollegeInsider.com Tournament.

The Lions became the first New York City school to win a postseason title since St. John’s won the NIT in 2003. The Red Storm later vacated that title. Columbia also became only the second Ivy League school to win a postseason crown.

Trailing 53-48 with 7:20 left, Columbia (25-10) scored 17 of the next 21 points. Mullins hit a 3-pointer and then on the next possession made an incredible shot, flipping the ball over his head as he was fouled on the drive. That three-point play gave Columbia a 54-53 advantage. Maodo Lo’s 3-pointer made it 63-57.

The Anteaters (28-10), who had won 18 of their past 22, could only get within four the rest of the way.

As the final buzzer sounded, the Lions celebrated the school’s first postseason title. Jeff Coby finished with 14 points and 10 rebounds for the Lions, who had the most wins in school history, including 15 non-conference victories.

Lo, who earned tournament MVP honors, added 13 points and finished third on the school’s all-time scoring list, 12 short of breaking the school record.

Trailing 20-14 with 8:52 left in the first half, Columbia used a 17-6 run to close the half and take a 31-26 lead at the break. Lo hit a 3-pointer to get the run started and Luke Petrasek’s 3-pointer made it 29-22.

Mamadou Ndiaye, the Anteaters 7-foot-6 center, then had consecutive dunks where he barely had to leave the ground to make it a five-point game at the half.

Mike Best scored 17 points to lead the Anteaters. Ndiaye finished with 14 points and eight rebounds.

NITValparaiso 72, BYU 70

New York — David Skara sank the tiebreaking 3-pointer with 20 seconds left and Valparaiso held off BYU to reach the championship game of the National Invitation Tournament.

Skara came off the bench to score a season-high 15 points, none bigger than his jumper that gave the top-seeded Crusaders (30-6) a 71-68 advantage after they had squandered a 16-point cushion.

Alec Peters also had 15 points for the Crusaders, who will play for the title Thursday night at Madison Square Garden against the winner of the second semifinal between George Washington and San Diego State.

Kyle Collinsworth paced the Cougars (26-11) with 20 points, five rebounds and five assists in his final college game. Nick Emery scored 18 and Chase Fischer added 16.
