OMAHA, Neb. — Turns out, Michael Beasley and O.J. Mayo weren't the only freshmen on the court.

Redshirt freshman Bill Walker scored 22 points, true freshmen Jacob Pullen and Ron Anderson also reached double figures, and Kansas State's Kiddie Corps moved on in the NCAA tournament, beating Mayo-led USC 80-67 in the opening round today.

Beasley overcame early trouble to have another big game for the Wildcats (21-11), scoring 23 points and grabbing 11 rebounds for the 27th double-double of his brilliant — and likely only — college season. The NBA beckons, after all.

But 11th-seeded Kansas State is used to big things from Beasley. It was his supporting cast that made the difference.

Walker carried the load in the early going, scoring 17 in the first half and hitting a dagger of a 3-pointer in the closing minutes. Pullen, a lightning-quick guard, scored 11 points and doled out five assists. Anderson, averaging only 3.1 a game, scored 10 and grabbed eight rebounds to help the Wildcats dominate the boards.

And don't forget yet another Kansas State freshman. Dominique Sutton stuck to Mayo like a nagging cold, helping limit USC's freshman star to 6-of-16 shooting. Mayo, who signaled his intentions by wearing NBA socks, scored a couple of late baskets to reach 20 points but it didn't matter.

Beasley put off his expected jump to the pros for at least one more game. The Wildcats moved on to face either No. 3 seed Wisconsin or No. 14 Cal State Fullerton in the second round Saturday.
