Freshman guard Trey Alexander scored seven of his game-high 18 points in overtime as ninth-seeded Creighton rallied past No. 8 San Diego State 72-69 in the first round of the NCAA Tournament's Midwest Region on Thursday night in Fort Worth, Texas.

Ryan Kalkbrenner added 16 points and 10 rebounds for the Bluejays (23-11) before he sustained a left knee injury midway through overtime and was helped from the court.

Alex O'Connell added 15 points, Arthur Kaluma scored 12 and Ryan Hawkins had 10 for Creighton, which will play top-seeded Kansas in the second round on Saturday. The Jayhawks routed 16th-seeded Texas Southern 83-56.

"I'm just so proud of these guys," Bluejays coach Greg McDermott said. "We lost Kalkbrenner and everyone stepped up. What this freshman (Alexander) did was incredible. It was a great program win."

Chad Baker-Mazara came off the bench to lead San Diego State (23-9) with 17 points. Matt Bradley scored 16 and Trey Pulliam added 14.

The Bluejays used a 9-0 run over the final 2:28 of regulation to force overtime. Alexander made a jumper in the lane to tie the score at 62-all with 11.2 seconds left.

"Even when we were down seven with two minutes to go (in regulation)," said Alexander, "everyone in the huddle was saying, 'We've been here before and we can do it.'"

Bradley was fouled while driving to the basket with 6.4 seconds to go but missed the ensuing free throw.

In overtime, Bradley made a free throw with 2:06 left to give San Diego State a 69-66 lead.

Alexander made a baseline jumper 19 seconds later, then was fouled while driving for a basket with 1:07 left and converted the foul shot to give Creighton a 71-69 advantage.

The Bluejays' KeyShawn Feazell made a free throw with 0.8 seconds left for the final margin. It was the only point scored by the Creighton bench, as the Aztecs' reserves enjoyed a 30-1 scoring advantage.

With starting point guard Ryan Nembhard, the Big East freshman of the year, sidelined because of a broken wrist, the Bluejays struggled to take care of the ball in the first half, falling behind by as many as 14 points at 35-21.

Creighton finished the half with a 9-2 run to pull within 37-30.

Baker-Mazara scored 15 of his 17 points in the first half.
