DALLAS (Ticker) -- Oklahoma State is one game away from the Big 12 Conference version of the daily double.
John Lucas scored 22 points as the seventh-ranked Cowboys pulled away in the second half and moved into the championship game of the Big 12 Conference tournament with an 82-77 win over Texas Tech.
Ivan McFarlin had 18 points and Daniel Bobik hit a series of key 3-pointers for the Cowboys (26-3), who will meet Texas in Sunday's final.
Oklahoma State won for the 16th time in 17 games and is trying to become the first Big 12 regular-season champ to win the postseason tournament since Iowa State in 2000.
"It feels great to get the chance (to play for the title)," Cowboys guard Tony Allen said. "I don't know when it was the last time that OSU won a conference title, but it would be great to take one back home."
The Cowboys have not won a conference tournament since the 1995 Big Eight title.
Andre Emmett scored 26 points for the Red Raiders (22-10), who were within five points with 5:30 remaining. But Oklahoma State went on a 9-4 run, including a 3-pointer by Bobik that made it 60-52. The Cowboys eventually increased the lead to 74-61 on a 3-pointer by Joey Graham with 1:37 left.
Oklahoma State closed the first half with a 17-3 run to take a 41-29 lead at intermission. The spurt began with a three-point play by Allen and included four 3-pointers, including a pair by Bobik.
"For him to step up like he did is just going to make us more and more dangerous," Lucas said of Bobik.
But it was the late first-half run that appeared to seriously damage the Red Raiders.
"Toward the end of the first half, it was like a bomb went off. Now we're down 12," Texas Tech coach Bob Knight said. "I had to be pleased with our team that we were able to get back in position in the last 10 minutes."
The loss snapped a three-game winning streak for Texas Tech, which beat Colorado in the quarterfinals on Friday. Texas Tech defeated Oklahoma State back in January and hopes that a respectable performance on Saturday might be enough for an NCAA Tournament at-large berth.
"To play as well as we played today, I think that will show the selection committee a lot on where we get seeded," forward Robert Tomaszek said.
