OKLAHOMA CITY ? Kansas University point guard Aaron Miles’ best shooting performance of the season left him wanting more.

“You have to put this in perspective,” Miles said after second-seeded KU defeated No. 10 Arizona State, 108-76, Saturday night at Ford Center in the second round of the NCAA Tournament. “You can celebrate a little, but you have to get back to practice and work. I think our team is mentally ready and focused to get back to practice and get ready for the next round — no matter who we play.”

The Jayhawks will meet third-seeded Duke Thursday in the Sweet 16 at Anaheim, Calif.

“We have got to be prepared,” Miles said. “We can’t be satisfied. Me, personally, I am not satisfied with what we’ve accomplished yet. We made a couple goals, and our biggest goal is to win the national championship.”

The Jayhawks didn’t play like champions in their previous two games. Miles scored only four points on 1-of-9 shooting in a 68-63 loss to Missouri last Saturday in the Big 12 Conference tournament semifinals at Dallas. He dislocated his finger in that game, then took only two shots and scored two points Thursday in KU’s 64-61, first-round NCAA victory against Utah State.

He played with his sore finger taped in the Utah State game and in Saturday’s victory, but it didn’t alter his shooting stroke against ASU. Miles’ 18 points were his most since a 20-point outing against Division II Central Missouri State in the fifth game of the season. Saturday, he finished 5-of-7 from the field, 6-of-8 from the foul line and sank both his three-point attempts.

The guard had been in a 3-of-21 skid from three-point range in a nine-game span.

“I was playing with a lot of confidence today,” he said. “My teammates were finding me. I was a lot more aggressive than normal, and I think that played a big part in my success.”

Miles had six of KU’s 21 assists as the Jayhawks shared the ball in their transition offense. ASU had faced its share of running teams in the Pac-10 Conference, but the Sun Devils could not keep up with Kansas.

The Jayhawks scored 20 points off 11 Sun Devil turnovers, outscored Arizona State 13-4 on fastbreak points and owned a 56-36 advantage on points in the paint.

“They might have been prepared for it,” Miles said of KU’s transition offense, “but we came out and executed it well.”

KU’s victory gave the Big 12 a sweep of the Pac-10 at Ford Center — Oklahoma defeated California 74-64 in Saturday’s first game.

Kansas had been 2-2 against the Pac-10 during the regular season with victories against UCLA and California and losses to Oregon and Arizona.

“The Big 12 Conference is a great conference,” Miles said. “The Pac-10 is a great conference also. You can say it made a statement, but it’s tournament time and everybody has to play. I felt like we stepped up and played better than them today.”

One of the few plays Miles didn’t like came with 5:30 remaining. ASU guard Jason Braxton stole the ball from Miles near midcourt, dunked over the Jayhawk guard at the other end and then talked trash — despite the fact KU led 94-59.

“I don’t know what he said, but it was personal,” said Miles, who had four turnovers in 32 minutes. “He picked my pocket and dunked on me. I don’t like getting my pocket picked, especially in the open floor.”

Miles, who yapped with Braxton during much of the game, answered with a layup a little more than a minute later, then sank a three-pointer on KU’s next possession.

“It was fun,” he said. “I hadn’t had fun like that in a while.”
