PARADISE ISLAND, Bahamas (AP) -- Oklahoma coach Lon Kruger knows the Sooners' offense will start to click better as the season goes along.
For now, their defense is more than enough.
Holding Butler to 24 percent shooting -- the best by an Oklahoma team in nearly 11 years -- the Sooners earned a berth in the Battle 4 Atlantis championship game by topping the Bulldogs 59-46 on Thursday, with Isaiah Cousins' 13 points leading a balanced offense.
"Our guys' awareness defensively was as good as it's been all year," Kruger said. "We really had five guys working together, which is what you're supposed to do on the defensive end."
Oklahoma (4-1) has held each of its opponents this season under 40 percent shooting. Butler's 14-for-59 performance was the worst against an Oklahoma team since Arkansas-Pine Bluff shot 9-for-44 in a 94-24 loss to the Sooners on Dec. 2, 2003.
Jordan Woodard and TaShawn Thomas each scored 10 points for the Sooners, who made their first 11 shots from 2-point range on the way to a quick 30-14 lead.
Oklahoma will face No. 2 Wisconsin in the title game Friday.
"That's what we came here for. That was our goal," Cousins said. "We're striving for greatness."
Kellen Dunham scored 17 points for Butler (4-1), which knocked off No. 5 North Carolina in the quarterfinals but went scoreless for an 8-minute second-half stretch against the Sooners.
"I'm not too concerned about that," Butler interim coach Chris Holtmann said. "I think our effort is there. We need to probably clean up a few things and we will, but I think we've played two good teams defensively, and I think Oklahoma has a chance to be outstanding defensively."
Butler missed its first four shots, then had an 0-for-8 drought later in the first half -- and what awaited the Bulldogs in the second was even worse.
Butler trailed by as many as 17 early but got the first two baskets after halftime to pull within 36-28 on Andrew Chrabascz's jump hook with 17:46 left.
That would be the last real hurrah for the Bulldogs.
After Chrabascz's basket, Butler would miss its next 13 tries from the floor, including eight misfires from around the rim.
And that was more than enough for the Sooners, who scored 11 straight points to go up 47-28 on Cousins' 3-pointer with 9:42 left.
"We couldn't make shots," Chrabascz said. "If a couple more shots went in, it could have been a completely different game."
