Oklahoma State's Phil Forte III and Le'Bryan Nash scored 21 points, including all 12 of the Cowboys' points in overtime, lifting them to a 74-72 victory over Missouri on Tuesday night.
Anthony Hickey Jr. added 12 points for the Cowboys (10-2), who rallied from a 12-point second-half deficit and then had to withstand the Tigers' own feverish comebacks.
Missouri (5-7) had a chance to take the lead late in overtime, but Tramaine Isabell -- whose 3-pointer with 2-tenths of a second left forced overtime -- turned the ball over.
Nash made two fouls shots with 5.4 seconds to go, and Oklahoma State fouled to prevent the Tigers from getting off another tying 3. Johnathan Williams III made the first of two free throws with 3 seconds left, and missed the second intentionally.
A tying floater bounced over the rim and harmlessly to the floor.
