Frank Mason III scored 17 points to lead a balanced attack, and the second-seeded Kansas Jayhawks rolled to a 75-56 victory over the No. 15 seed Aggies on Friday, giving their beleaguered Big 12 its first NCAA Tournament victory in four tries this March. Kansas coach Bill Self, whose team had twice failed to hit a single 3-pointer in games during the last few weeks of the season, said, "It was nice to see the lid come off the basket." Perry Ellis added nine points for the Jayhawks, who also did their part in setting up a tantalizing matchup with seventh-seeded Wichita State in the Midwest Region's round of 32.
