NORMAN, Okla. - After nearly coming all the way back from a 19-point deficit, the Kansas Jayhawks just couldn't prevent another frustrating loss.

Terrell Everett scored 19 points and freshman David Godbold added a career-high 15 in No. 22 Oklahoma's 71-63 victory Monday night that sent the eighth-ranked Jayhawks to their first three-game losing streak in nearly 11 years.

Kansas, which lost to Texas Tech in double overtime and Iowa State in overtime last week, has lost three straight for the first time since falling to Oklahoma State, Missouri and Nebraska from Feb. 16-23, 1994. The Jayhawks haven't lost four in a row since an eight-game losing streak in 1988-89.

"I think we're a tough team," freshman guard J.R. Giddens said. "We're just going through some things right now like a lot of teams do. I wouldn't say our season's over with.

"We're not done. The Jayhawks are not done."

In other games involving Top 25 teams Monday night, New Mexico beat No. 13 Utah 65-54, No. 17 Connecticut topped Notre Dame 88-74, and No. 25 Nevada beat Tulsa 70-56.

Kansas rallied from 19 points down in the first half to get within a point midway through the second half, but the Sooners (20-6, 9-4 Big 12) held on to drop the Jayhawks (20-4, 10-3) out of a first-place tie with Oklahoma State in the Big 12.

After trailing 37-18 with 1:10 left in the first half, the Jayhawks scored the last four points before intermission and the first five of the second half.

Struggling against Oklahoma's man-to-man defense, the Jayhawks found something that worked.

"Kansas in the second half kind of scrapped their offense," Oklahoma coach Kelvin Sampson said. "They didn't have any offense in the second half. They just put their head down and went to the rim."

The Jayhawks used an 11-2 rally, capped by Giddens' 3-pointer off a pass from Wayne Simien, to pull to 47-46. Aaron Miles started the run with four straight free throws, and Giddens and Simien followed with jumpers.

But once the Jayhawks got close, the Sooners switched to a zone and stymied Kansas' hopes for its biggest comeback win of the season.

Oklahoma scored six straight points to stretch the lead to 60-52, with Godbold grabbing a rebound and hitting a jumper in the lane with 2:33 left.

The Jayhawks got within four on several occasions after that, but Drew Lavender hit all four of his free throws and Everett added two more to secure the victory.

"We were horrible and OU was good defensively," Kansas coach Bill Self said. "I thought they played with great energy, and I thought they did a great job defensively of not letting the ball get in tight. We did a bad job of driving it and creating help.

"It was just pitiful. Pitiful all the way around. But their defense had a lot to do with it."

Simien finished with 17 points and six rebounds, Keith Langford scored 16 points and Miles added 12 for Kansas.

Oklahoma took control early as Kansas turned the ball over five times in the first eight minutes. Lawrence McKenzie's 3-pointer finished a 15-2 run that gave Oklahoma a 18-6 lead. After a 3-pointer by Everett on the next possession, McKenzie hit another 3 to make it 24-9.

The Sooners pushed ahead further with an 8-2 run that Gilbert capped with a layup, and they led 37-18 before the Jayhawks started their rally.

Sampson thought his team showed mental toughness by holding off the Jayhawks' comeback.

"You just can't have any fear in those situations," Sampson said.
