WACO, Texas (Ticker) -- John Lucas saw firsthand how far his former team has come in a span of two weeks.
After handing Baylor its worst loss of the season on February 14, sixth-ranked Oklahoma State had a much tougher time with the Bears before emerging with a 72-65 victory in a Big 12 Conference game.
Ivan McFarlin scored a season-high 24 points and Tony Allen added 22, including a 60-foot basket at buzzer, to lead Oklahoma State (22-3, 12-2), which will host Texas in a showdown for first place in the Big 12 on Monday.
Baylor (8-19, 3-11) rallied from a 12-point deficit in the final 4:24 and pulled within 67-65 with a minute left after back-to-back 3-pointers by Harvey Thomas.
But Baylor transfer Lucas did not allow the Cowboys to lose, penetrating past three players in the lane and setting up McFarlin for an easy layup with 25.8 seconds remaining, just before the shot clock expired.
Baylor missed three 3-point attempts on its final possession. Allen rebounded the final miss and heaved the ball to the other basket just before the buzzer as he fell to the floor. The ball swished through the net.
Lucas transferred from Baylor in the offseason in the wake of the scandal surrounding slain former Bears player Patrick Dennehy. Due to the circumstances, the 5-11 junior was not forced to sit out a year and was immediately eligible for the Cowboys.
Lucas scored 13 points in Oklahoma State's 91-58 rout of the Bears at Stillwater. On Saturday, he hit just 3-of-10 shots for seven points and added seven assists.
McFarlin scored 18 of his 24 points in the first half. Allen took over in the second half, when he had 20 of his 22. The two combined to shoot 20-of-32 from the field.
Oklahoma State shot 58 percent in the second half, but Harvey Thomas and Terrance Thomas kept Baylor within striking distance. Harvey Thomas scored 24 points on 9-of-13 shooting and Terrance Thomas had 22 on 8-of-14 shooting, including 4-of-5 from 3-point range.
The Cowboys raced to a 15-8 lead in the first seven minutes as McFarlin dominated inside for three layups and two dunks.
But a 3-pointer by R.T. Guinn, a jumper by Harvey Thomas and a free throw by Matt Sayman gave Baylor its first lead at 26-25 with 2:35 left in the half.
Oklahoma State held its biggest lead at 65-53 on a layup by Allen with 4:24 left.
