Pendarvis Williams and Chris McEachin each added 20 points for the MEAC champion Spartans (26-9), who made their first trip to the NCAA tournament a memorable one. They became the fifth No. 15-seeded team to topple a No. 2 and the first since fellow conference member Hampton knocked off Iowa State in 2001. O'Quinn had a chance to put the game away when he went to the foul line with 3.8 seconds to go, but the 70% free throw shooter missed both. Missouri called a timeout with 2.9 seconds to go and got the ball in the hands of Phil Pressey, but his long three-pointer from the wing bounced off the back iron as the final buzzer sounded.
