LUBBOCK, Texas (Ticker) -- Tony Allen single-handedly ended a surprising stretch of ineptitude by Oklahoma State.
Allen came up with six straight points in a late 75-second span as the 17th-ranked Cowboys stretched the nation's longest winning streak to 14 games with a 79-70 Big 12 Conference victory over No. 25 Texas Tech.
Oklahoma State (16-1, 5-0 Big 12) never trailed in the second half, leading by as many as 15 points. But the Cowboys got sloppy holding the lead and committed a series of turnovers that allowed the Red Raiders to stay close.
Texas Tech (11-4, 1-3) used a 12-2 run to pull within 65-64 on Andre Emmett's turnaround jumper with 3:13 remaining. Allen used his quickness to go straight to the basket on the next possession and give the Cowboys a three-point lead 17 seconds later.
"Allen's a very good player who made some good plays," Texas Tech coach Bob Knight said. "They played very hard and really well, which is what we've seen."
Allen added a driving layup and came up with a steal and an uncontested basket for a 71-64 advantage, prompting a timeout by the Red Raiders. Allen went straight to pumped-up Cowboys assistant James Dickey, who was making his return to Lubbock, where he compiled a 166-124 record from 1991-2001 with Texas Tech.
The game pitted two coaches who have won over 700 games in Knight and Cowboys mentor Eddie Sutton. The coaches have split eight meetings.
Victor Williams led Oklahoma State with 24 points and Allen finished with 21 and five of the team's 12 steals. Melvin Sanders chipped in 17 points as the Cowboys' athletic trio created an 18-4 edge in fast-break points.
Sanders went coast-to-coast for a resounding dunk and Allen added a steal and a slam as Oklahoma State took its first double-digit lead at 26-16 with 6:16 left before halftime.
The Red Raiders rallied and Ronald Ross' layup capped a 13-2 run for a 35-34 lead with 30 seconds to go. But Williams drained a 3-pointer just before the halftime buzzer to give the Cowboys a two-point lead.
"(It was) a big basket at the end of the first half," Knight said. "Our starts to the second half were diametrically opposite. Their start was very good, very energetic, and ours was filled with errors."
Williams scored the Cowboys' first eight points of the second half, including a pair of buckets to trigger a 14-0 tear. That run was highlighted by three straight dunks to end it - two by the high-flying Sanders and one by Allen.
Sanders split a pair from the line for a 63-52 advantage with 8:20 remaining before Oklahoma State started to sputter. The Cowboys had five straight turnovers at one point and Williams finished with eight of their 20 for the game.
Kasib Powell led Texas Tech with 26 points on 10-of-16 shooting and Emmett added 23. The Red Raiders suffered their fist loss in eight home games.
"They had built big leads in both the first half and second half and we came back both times," Knight said. "Usually, a good team is going to come back."
