Wichita State, Kentucky, Stanford, Kansas advance

Even with just a so-so offense, Wichita State cruised to a historic 35th win in a row largely because they never quit on defense. That'll come in handy when the competition steps up Sunday against preseason No. 1 Kentucky.

Cleanthony Early had all but four of his 23 points in a dominating first half against a first-time NCAA entrant.

Julius Randle had 19 points and 15 rebounds for No. 8 seed Kentucky (25-10) in a 56-49 victory over Kansas State.

Andrew Wiggins scored 19 points and Jamari Traylor and Perry Ellis had double-doubles for No. 2 seed Kansas in an 80-69 victory over pesky Eastern Kentucky.

Stanford made the most of its first NCAA appearance since 2008, starting fast and finishing strong to earn a date against Kansas. New Mexico made another hasty exit.
