STILLWATER, Oklahoma (Ticker) -- Oklahoma State and John Lucas truly enjoy all the comforts of home.
Lucas scored 25 points as No. 7 Oklahoma State extended the nation's longest home winning streak to 28 games with an 85-56 victory over No. 25 Texas Tech in a Big 12 contest.
The Cowboys (20-3, 10-2 Big 12) have won their last six games and moved into a first-place tie with Kansas atop the conference standings after the Jayhawks were upset in overtime by the Iowa State Cyclones, 63-61, earlier in the day.
"We are fighting for a Big 12 championship," Lucas said. "Iowa State helped us out today. We had to come in here and win. Coach was saying the ball was in our court."
Oklahoma State coach Eddie Sutton recorded his 26th 20-win season and won his 775th game by defeating Texas Tech's Bob Knight in a matchup of two of the seven winningest coaches in Division I history.
The Cowboys scored 12 of the first 16 points and shot 47 percent (15-of-32) to take a 35-26 lead at intermission. Lucas and Joey Graham combined for 17 of Oklahoma State's points in the opening half.
Lucas opened the second half with a 3-pointer from the left corner, which prompted an angry Knight to call a quick timeout. But the Cowboys stayed hot with JamesOn Curry capping a 19-6 run with seven straight points to take a 54-32 lead with 13:30 remaining.
Lucas made three more 3-pointers later in the second half as Oklahoma State won for the 15th time in the last 19 meetings against Texas Tech.
"They are probably the hardest team in the league ... to defend," Cowboys assistant James Dickey said. "Our guys really worked hard and did a good job. That is the best we have defended Texas Tech since coach Knight has been there."
Curry scored 15 points and Ivan McFarlin added 12 with 11 rebounds and four blocks for the Cowboys, who shot 52 percent (33-of-64) from the floor and had a 40-32 rebounding edge.
"We just came out and played," McFarlin said. "We did not worry about making mistakes. We just came out and had fun. That is what Oklahoma State basketball is about, having fun and playing great defense."
Martin Zeno scored 19 points and Devonne Giles added 12 for Texas Tech (16-7, 8-4), which lost for the second time in its last seven outings.
"Their defense was as good as I have seen in a long time," Knight said. "The way they pressured, the way they moved and the way they worked. That was the main difference in the game."
