Overtime belonged to San Diego State was the Frogs fell 98-92 at the hands of the nation's 21st ranked team.
As a result, TCU seniors leave the floor at Daniel Meyer Coliseum for the last time with a loss.
The good news: TCU basketball was back. The bad news: The loudest DMC crowd in a long time went home after a loss.
The Frogs trailed by 12 at halftime after shooting just 32 percent from the floor. Meanwhile San Diego State connected on 17 of their 30 attempts in the first half.
As was the case in the Frogs recent come-from-behind victory over UNLV, TCU trailed by 18 at the 15 minute mark in the second half.
Just like that game, TCU turned it up behind hot shooting from Hank Thorns. Thorns finished his last game at Daniel Meyer Coliseum with 25 points. Fellow senior J.R. Cadot finished with 24, a career high.
The difference from the UNLV game was that San Diego State had Jamaal Franklin. Likely to be the Mountain West Conference player of the year, Franklin hit 14 of 17 free throws including timely shots down the stretch which put the game away for the Aztecs.
Franklin is one of the nation's most improved players. He has improved his scoring by 13.59 points per game and his rebounding by 5.94 board per game.
"I know we are definitely going to try to improve on our defense going into the tournament," senior Craig Williams said. "We brought things back but just couldn't pull it off at the end."
Head coach Jim Christian echoed Williams comments. He noted that his team gave San Diego State way too much of a head start in the first half.
"We went up 3 with under a minute to go. We did a good job forcing a bad shot. We just have to get that rebound," Christian said. "In the first half it was just one-on-one defense that they were abusing us on."
"I thought Garlon [Green] did a great job on Franklin limiting his touches in the second half," Christian said.
The Frogs had their opportunities. San Diego State head coach Steve Fisher said it looked like the Frogs were going to pull it out toward the end of regulation.
"We have to do a little better job being opportunistic," Christian said.
The Frogs will now travel to Las Vegas for the Mountain West Conference tournament next week. The Frogs will be the five seed and will play Colorado State in the first round.
The Frogs capped their winning regular season since 2004-2005 when TCU went to the NIT.
"Jim Christian is a great coach, and they are lucky to have him here," San Diego State coach Steve Fisher said. "He has shown what he can do with the right resources and time."
"I knew. Our coaches knew, but I'm not sure our players knew when we hit the first two baskets of the second half, and we're up 16. They take a timeout. They weren't going to go away. We saw what they did to Vegas. We saw the way they took a close game and created huge separation against New Mexico. This is a team that competes, and when they make three like they did in the second half, they are going to get back, and get back in a hurry," Fisher said.
"I know how Jim feels. He has done a magnificent job with his team this year, and with the way he has grown the program," Fisher said.
Fisher's Aztecs finish the Mountain West Conference with the best record. They will be the number one seed in the Mountain West tournament.
New Mexico is the 2 seed. UNLV is the 3 seed, and Colorado State will be the 4 seed.
TCU will play Colorado State on Thursday afternoon in Vegas.
