DALLAS (Ticker) -- Travon Bryant hit a fallaway lane jumper at the buzzer, giving Missouri a dramatic 60-58 victory over No. 25 Oklahoma State in the quarterfinals of the Big 12 Conference tournament.
Bryant's basket snapped the game's 13th tie and came after Oklahoma State played stellar defense on the final possession.
With time running down, Jimmy McKinney drove the right side but was shut off and had the ball knocked away. However, it ended up in the hands of Bryant, who launched a 12-footer in the lane with just over a second left.
The ball bounced on the rim before dropping through the basket as time expired, sending Missouri (20-9) into a semifinal meeting with Kansas on Saturday. The Tigers reached 20 wins for the third straight season.
"Coach (Quin Snyder) wanted us to get the last shot," Bryant said. "When I saw the opening, I thought, 'Let me get the ball if it misses.' My first instinct was to put the ball back up. I knew the ball was going up when I saw Jimmy drive right. I tried to be aggressive to get position in case it came off the rim."
"They jammed McKinney and made him give it up," Snyder added. "He made a heads-up play driving the ball. I'm happy we got a break tonight. We hadn't gotten a lot of those this year and we almost didn't win this game."
McKinney scored 16 points and Arthur Johnson added 12 for Missouri, which will be playing its third game in as many days against the Jayhawks. The Tigers beat Nebraska in the first round on Thursday.
"Now we've put ourselves in a position to go out and do something special," Bryant added.
Victor Williams scored 12 points and Melvin Sanders and Andre Williams added 10 apiece for Oklahoma State, which will go into the NCAA Tournament having won just five of its last 12 games.
"Usually, when you go for one shot like Missouri did, it's not the first shot that kills you, it's the second," Oklahoma State coach Eddie Sutton said. "We didn't block out."
Friday's contest featured 14 lead changes with neither team holding more than a three-point advantage in the second half.
Oklahoma held Missouri to 43 percent shooting (23-of-54) and limited Tigers leading scorer Rickey Paulding to 10 points, seven below his average. Ricky Clemons had just 11 points, five fewer than his average.
"We did an excellent job on defense and the guys we thought we'd have to stop," Sutton said. "But the guy that hurt us was McKinney. He was terrific today."
The freshman guard nearly doubled his average of 8.5 points per game and committed just one turnover in 38 minutes.
"Jimmy was our leader tonight," Paulding said. "He was definitely ready to shoot and did a nice job of orchestrating the offense."
The Cowboys (21-9) took a 58-55 lead on Ivan Mcfarlin's foul shot with 2:32 left, but McKinney scored on a driving layup while being fouled and hit the free throw to tie it for the final time with 1:47 left.
Oklahoma State had a chance to take the lead on its next possession, but Johnson blocked Mcfarlin's jumper with 1:20 to go.
Paulding's baseline went in and out with 53 seconds to go before Sanders missed an open jumper on the right baseline with 35 seconds remaining, giving the final possession to Missouri.
"This is definitely a difficult loss and an emotional game," Victort Williams said. "We have no choice but to get over this game and get ready for the big dance."
Paulding's 3-pointer snapped a 52-52 tie with 3:55 remaining, but Victor Williams answered with a 3-pointer from well beyond the arc as the shot clock was about to expire.
Mcfarlin, who also grabbed 14 rebounds, converted a pair from the line to give the Cowboys a 57-55 lead with 2:32 left. He made only 1-of-2 on Oklahoma's next trip to keep it a one-possession game.
"Everything we did positive today is overshadowed by the end result," Sanders said. "There were a couple positives but a lot to (take) back to practice and work on."
