NORMAN, Okla. — Travis Releford scored 28 points to set a career best for the second straight game, Thomas Robinson added 18 points and No. 14 Kansas used a big surge just after halftime to beat Oklahoma 72-61 Saturday.
The Jayhawks (12-3, 2-0 Big 12) scored the first seven points of the second half to take the lead, then never gave it back. Jeff Withey, Elijah Johnson and Robinson all had two-handed slams during a 29-6 surge that turned a one-point game into a blowout.
The Jayhawks have won their first two conference games for the sixth straight year and the 16th time in 17 seasons.
Steven Pledger scored 14 points to lead the Sooners (10-4, 0-2), who have lost three of their last four games.
Kansas has won the last eight games in the series.
Releford had career-highs with 16 points and 11 rebounds, notching his first double-double, in his previous game against Kansas State and continued his strong start to Big 12 play. He had eight points during Kansas' decisive run.
Tyshawn Taylor drove the left baseline for a three-point play and Johnson drilled a 3-pointer from the left wing to finish the Jayhawks' big run and make it 62-40 with 8:37 remaining.
The Sooners missed eight of their first 10 shots and committed five turnovers in the first 8 minutes of the second half to allow Kansas to get out and run. Romero Osby practically handed the ball to Robinson on Oklahoma's first possession after the break, and Robinson raced to the opposite end for a layup.
The Jayhawks got eight of their first 11 second-half points on the fast break, and then took turns setting each other up for dunks. Releford fed Withey for his dunk, Taylor lobbed to Johnson for a throwdown and then Johnson tossed an alley-oop for Robinson.
The Sooners gave up a huge run to open the second half for a second straight game. Missouri outscored the Sooners 37-13 right after halftime to salt away an 87-49 victory that was already a blowout.
This time, neither team led by more than five points in a first half that featured eight lead changes.
Releford matched his previous career-high for a game with 16 points before halftime, but Oklahoma took a 34-33 lead at the break after Osby hit a right-handed hook shot to answer Robinson's reverse layup. It was the last time Oklahoma would be ahead.
Andrew Fitzgerald had 11 points on 5-for-16 shooting and Carl Blair scored nine of his 11 points in the final 6 minutes as the Sooners tried to claw back into it.
