STILLWATER, Oklahoma (Ticker) -- Oklahoma State, one of the top shooting teams in the nation, used big second-half surge to avoid an early-season upset.
John Lucas scored 22 points and Joey Graham added 16 as the seventh-ranked Cowboys posted a 90-65 win over a hot-shooting Arkansas-Little Rock squad.
With Oklahoma State leading, 32-31, at halftime, Lucas sparked a 20-8 run over the first 5:12 with three straight 3-pointers.
"In the second half, we started to shoot the ball better as we shared it more," Oklahoma State guard Stephen Graham said. "It shows when you start to play Cowboy basketball."
Overall, the Cowboys (2-0) made 34-of-62 shots (55 percent) but struggled on free throws, missing 14-of-27 attempts.
Lucas finished 8-of-14 from the field, including 4-of-7 from the arc, with seven assists. Center Frans Steyn added 11 points and three steals for Oklahoma State.
"Any time you have an inside presence, you put a lot of pressure on the other team," Cowboys guard Daniel Bobik said. "Having someone like Frans inside and our other guys down low really helps out our ball club."
Bill Freeman scored 25 points on 10-of-15 shooting with five 3-pointers for the Trojans (1-1), who made five of their first six 3-pointers en route to a 52 percent (13-of-25) shooting performance in the first half.
Zack Wright chipped in 14 points for Arkansas-Little Rock, which fell to 0-4 all-time against Oklahoma State.
"We knew coming in here that we were going to face great pressure," Arkansas-Little Rock coach Steve Shields said about his team's 19 turnovers. "Coach Sutton's teams are always fundamentally sound. They always make it tough to score and I think they did a good job of that in the second half."
