Columbia, Mo. Oklahoma State kept the ball in Byron Eaton's hands the final half-minute. The junior guard didn't disappoint with his second straight game-winner.
Eaton killed most of the clock near center court in a tie game and then scored off a drive near the lane with 1.7 seconds to go after buying some space with a pump fake in the Cowboys' 75-73 victory over Missouri on Tuesday night.
"He made a big-time play," coach Sean Sutton said. "We switched out on a ball screen, he drove it, and made an unbelievable shot."
Leo Lyons returned to Missouri's starting lineup after a 10-game absence and had career bests of 27 points and 18 rebounds. The 6-foot-9 Lyons missed only one of 13 shots, many of them from the perimeter, but it wasn't enough in a battle of Big 12 also-rans angling for a higher seed in the conference tournament.
"Both halves he was focused," coach Mike Anderson said. "He was really into the game, you could just see it with his body language."
Missouri led by eight points midway through the second half but couldn't hold on as Oklahoma State hit a season-high 14 three-pointers in only 24 attempts.
"That was probably one of the tougher ones all year long," Anderson said. "We played well enough to win and just didn't finish the deal."
Marcus Dove led Oklahoma State (15-12, 6-7 Big 12) with 15 points and 10 rebounds, his first double-double of the season and only his second time in double-figure scoring in nine games. Eaton was 4-for-6 from three-point range, and Dove and Terrel Harris both were 3-for-3.
"When we're on, we're on," Dove said. "We have great shooters, we really work on that a lot."
Eaton had 15 points, and freshman James Anderson added 13 points in his first game off the bench for the Cowboys.
