TULSA, Oklahoma (Ticker) -- Nick Collison put together his best effort in the nick of time for Kansas.
Collison scored a season-high 26 points to lead a balanced attack as the 19th-ranked Jayhawks snapped a three-game skid against Division I foes with an 89-80 victory over No. 18 Tulsa, which suffered its first loss.
Kansas (4-3) entered with losses in three of its last four games, and the only win was over Division II Central Missouri State. The Jayhawks were in danger of falling below .500 after seven games for the first time in 30 years.
Tulsa (4-1) had a sellout crowd present at the Reynolds Center and four senior starters on a team that has averaged 27 wins over the last four seasons. The Golden Hurricane took a 40-36 halftime lead on Antonio Reed's 33-foot buzzer-beater.
The Jayhawks opened the second half on a 14-5 tear and Keith Langford's dunk with 16:48 remaining gave them the lead for good. Collison's two foul shots capped the spurt for a 50-45 edge.
A pair at the line from Jarius Glenn pulled Tulsa within 66-63 before Wayne Simien converted a three-point play, Collison threw in a hook and Aaron Miles made a 3-pointer in a 9-2 run.
Kansas had been 2-of-9 from the arc before Miles' 3-pointer with 4 1/2 minutes to go provided a 74-65 lead.
The Jayhawks improved to 6-0 against Tulsa. It was only Kansas' second visit to Tulsa and first since the 1953-54 season.
Simien and Langford each added 19 points as Kansas dominated inside. Collison grabbed 12 rebounds as the Jayhawks held a 41-32 edge on the glass, grabbing 19 offensive rebounds.
The Jayhawks' advantage in the paint was rewarded with numerous trips to the foul line as they converted 24-of-36. Collison made all eight attempts and Miles drained all six.
Kevin Johnson fouled out with 23 points and six rebounds for Tulsa, which shot 52.5 percent (32-of-61). The Golden Hurricane were 8-of-12 from beyond the arc but could not overcome 22 turnovers.
Kansas won despite a rough outing from star guard Kirk Hinrich, who made just 2-of-11 shots for four points. Miles picked up the slack with 15 points and eight assists. Hinrich did come up with five of the Jayhawks' 15 steals.
Jason Parker netted 15 points and Dante Swanson added 14 for Tulsa. Reed had a difficult time with Miles' defense, managing just eight points to go with eight turnovers.
