SAN ANTONIO (AP) Upsets abound in this NCAA tournament. Except in Texas.

While seven double-digit seeds busted brackets elsewhere, every higher seed in San Antonio has so far survived: Baylor and Creighton advanced in the West Regional to Sunday, when North Carolina and Iowa State will face off in the East.

Yet the second round at the AT&T Center was no snooze: the Tar Heels barely squeaked past No. 11 seed Providence and Louisiana Lafayette put a scare into third-seeded Creighton. Baylor beat 11th-seeded Nebraska, but only after officials tossed Big Ten coach of the year Tim Miles over a shot clock error they later acknowledged.
