STILLWATER, Okla. -- After No. 17 Oklahoma State rallied to force a second overtime Saturday against Texas Tech, coach Sean Sutton had a message for his Cowboys.
"I reminded them that we've done this before two other times," Sutton said.
As they did in those two previous multiple-overtime games, the Cowboys emerged winners, beating Texas Tech 93-91 thanks in large part to Mario Boggan's 35 points and 14 rebounds.
Oklahoma State (19-5, 5-4 Big 12) rallied from 11 points down in regulation and trailed by seven with 1:30 left in the first overtime before having a chance to win in the final seconds of the period. Tech's Martin Zeno blocked a layup attempt by Marcus Dove to force a second overtime.
The Cowboys scored the first six points of the second overtime to take an 89-83 lead, but Texas Tech (15-10, 4-6) rallied to tie it at 89 on a breakaway layup by Michael Prince with 33.9 seconds left.
Oklahoma State held for a final shot. David Monds missed a 15-footer, but Boggan rebounded and scored while being fouled with 4.1 seconds left. He made the free throw.
"When you're in a position to block out, you've got to block out," Texas Tech coach Bob Knight said.
Dove fouled Tech's Jarrius Jackson near midcourt with 1.3 seconds left, and Jackson made both free throws. The Red Raiders fouled JamesOn Curry on the ensuing inbounds play, and he hit the first of two free throws. After he missed the second, Zeno's desperation heave fell well short.
"It's a game we had to have. We could not afford to lose a game on our home court," Sutton said. "Our guys showed a lot of grit and a lot of courage."
Coming off consecutive road losses to Colorado and Oklahoma, the Cowboys extended their winning streak at Gallagher-Iba Arena to 17 games. Oklahoma State is 4-0 in overtime games this season, having also beaten Missouri State in one overtime, Pittsburgh in two overtimes and Texas in three overtimes.
The Cowboys hadn't gone 4-0 in overtime games since the 1964-65 season.
"Going into overtime gave us a surge of energy," Boggan said. "The conditioning in practice and learning how to focus really was what won the game for us."
Texas Tech has lost five straight since consecutive wins over ranked foes Kansas and Texas A&M. The Red Raiders have lost seven of eight against Oklahoma State and 18 of the last 23 meetings.
Knight addressed reporters for a little more than three minutes after the loss.
"Anytime that you're in overtime you can pick out 50 things during the course of the game that would have enabled you to win it," Knight said.
Jackson led the Red Raiders with 24 points, while Zeno added 21 points, 11 rebounds and six steals. Zeno also had half of Texas Tech's 12 turnovers.
A 15-2 run, highlighted by two 3-pointers from Darryl Dora, gave Texas Tech a 50-39 lead with 15:13 left. Oklahoma State answered with eight straight points as Boggan hit a pair of 3-pointers, including one that hit off the back of the rim, caromed above the backboard and dropped through the basket.
"Shooter's touch," joked Boggan, who set a career high with three 3-pointers in five attempts.
The Cowboys regained the lead at 59-56 on a 3-pointer by Curry with 7:26 left.
Texas Tech led 71-68 with 1:24 to go in regulation, but the Cowboys tied it on Byron Eaton's free throw with 31.2 seconds left. The Red Raiders had a chance to win in regulation, but Dora missed a well-guarded 18-footer at the buzzer.
In the first overtime, Texas Tech had what appeared to be a comfortable, seven-point lead with 90 seconds left. The Red Raiders still led 83-77 with 50.7 seconds to go, but the Cowboys closed with a flourish thanks to baskets off two late steals.
Boggan's three-point play, after he rebounded a missed free throw by Curry, cut the margin to two, and Curry scored after Zeno turned the ball over while being double-teamed.
Jackson missed a layup for Tech before Zeno blocked Dove's last-second shot.
"If it was last year, we probably would have given up," said Oklahoma State's Terrel Harris, who scored 16 points. "This year is different because we know a game is not over until the clock reads zero."
Curry also scored 16 points for Oklahoma State, which finished 20-of-30 from the free-throw line, compared to 27-of-31 for Texas Tech.
Charlie Burgess had 17 points and Jon Plefka added 16 for the Red Raiders. Three Texas Tech players fouled out -- including Plefla and Dora, the Red Raiders' two inside starters -- while Oklahoma State lost one player to fouls.
Sutton shook up his starting lineup, giving guard Tyler Hatch -- a former walk-on -- his first career start and replacing center Kenny Cooper with Monds, who had come off the bench in the Cowboys' previous nine games. Eaton, the usual starting point guard, didn't get off the bench until 9:59 remained in the first half.
The Cowboys led 33-31 at halftime.
