STILLWATER, Oklahoma (Ticker) -- No. 7 Oklahoma State needed a wake-up call in the second half to avoid a huge upset at home.
Joey Graham scored 18 of his 25 points after intermission as Oklahoma State recovered from a dismal first half to post a 73-57 victory over Sam Houston State.
The Cowboys (3-0) scored the game's first eight points but soon fell victim to a vicious 3-point attack from Sam Houston State and fell behind, 35-29, at halftime.
"We knew they were going to be an aggressive team," Graham said of the Bearkats, who got 28 points from their bench in the first half. "We knew they could shoot the ball a ton. In the first half we did not pick up on things as expected. In the second half, we just came out and covered some things up."
Graham set the tone five seconds into the second half with a jumper to kick off a furious rally. His hook shot less than four minutes in gave Oklahoma State a 38-37 lead and his dunk with 11:30 left put his club ahead to stay, 45-44.
Graham scored 10 points in the final 11 minutes as the Cowboys pulled away to extend their home winning streak to 19 games.
"We challenged him at halftime and I thought he really responded in the second half," acting Oklahoma State coach Sean Sutton said. "That is the Joey Graham we expect to see every night and the last 20 minutes he played like the type of player he was at times last year."
John Lucas recovered from a rough shooting start to score 17 points and Ivan McFarlin added 12 for Oklahoma State, which has outscored its opponents in the second half by an average of 22.3 points through three games.
Lucas converted four of his five 3-pointers in the final 12:39 and made four steals overall.
"(Graham and Lucas) are definitely All-American players," Sam Houston State coach Bob Marlin said. "I have seen new life in John (Lucas) and he has done a great job as a leader by getting the Cowboys to the Final Four last year and is going to be a great player for them this year."
The Bearkats made 8-of-15 shots from beyond the arc in the first half, the last by Othella Alford with 3:25 left to cap a 17-5 run and give Sam Houston State its largest lead, 33-24.
Alford scored 13 points but just two in the second half. Joe Thompson made 4-of-6 from 3-point range and scored 12 points for the Bearkats, who shot 46 percent (10-of-22) from 3-point range but just 43 percent (22-of-51) overall.
"I thought we had the game where we wanted it and with about seven minutes to go the game slipped away," Marlin said. "Lucas hit some big threes late and we got outscored, 17-9, to end the game."
"They wanted it more than us in the second half," said Sam Houston State freshman guard Brandon Streeter, who scored just two points and turned the ball over four times. "They were hungrier than us and they made us pay for it."
