LAWRENCE, Kan. -- Darrell Arthur scored 23 points, and Russell Robinson had 22 and helped fuel a 17-6 spurt in the second half that pulled No. 4 Kansas away from stubborn Baylor and carried the Jayhawks to a 100-90 victory Saturday night.
Despite its second-highest point total of the season, Kansas (23-1, 8-1 Big 12) was 0-for-9 from behind the arc and failed to hit a 3-point bucket for the first time since 2000 -- a span of 238 games.
The Jayhawks trailed by as many as seven points in the first half as Baylor guards Curtis Jerrells and LaceDarius Dunn kept hitting from the outside and silencing the typically loud sellout crowd.
When Dunn connected for a rare four-point play about 7 minutes into the second half, it was tied 50-all. But then Mario Chalmers, taking a long pass from Darnell Jackson, dropped in a short jumper and Sherron Collins followed with a three-point play to ignite the take-charge spurt that assured Kansas of its 11th victory in its last 12 meetings with Baylor.
The Bears (17-5, 5-3), nationally ranked two weeks ago for the first time in 39 years, lost for the third time in four games and fell to 0-8 in Allen Fieldhouse, where the Jayhawks have won 21 in a row overall.
Baylor had 12 3-pointers, including five by Dunn and four by Jerrells, who totaled 30 points.
Arthur's bucket gave Kansas a 50-46 lead, but Dunn tied it at 50-all when he hit a 3-pointer from the top of the key as he was fouled by Brandon Rush and subsequently sank the free throw.
Dunn had 23 points for Baylor and Henry Dugat had 15.
Collins had 17 points and was also key in the take-charge spree, hitting a bucket for a 63-56 lead, then grabbing a bucket and feeding Rush for a fast-break basket. After a Baylor turnover, he drove inside for an easy basket that gave the Jayhawks their biggest lead, 67-56.
The lead reached 81-66 a few minutes later on Darnell Jackson's dunk.
Baylor's 85 points were the most this season by any Kansas opponent and the second half was the highest-scoring half of the season for either teams.
The Jayhawks, who have won at least 23 games 19 years in a row, did not have a single rebound the first few minutes while the Bears had seven and seized a 10-4 lead -- the biggest deficit Kansas had faced in any home game this season.
Kansas clipped the lead down to one point a few minutes later on buckets by Rush and Arthur, but then Jerrels and Dunn hit back-to-back 3-pointers to boost the lead to 20-13.
Robinson's bucket ignited a 7-0 run that tied it 20-20 before another Jerrells 3-pointer put Baylor back on top.
Mario Chalmers had nine points for Kansas and Arthur had 10 rebounds. Brandon Rush, playing without a brace on his right knee for the first time since undergoing ACL surgery last June 1, had nine points and seven rebounds. He threw a scare into the crowd at one point when he slipped and fell down, apparently without re-injuring the knee.
