Trey Kaufman-Renn tipped in a miss by Braden Smith with 0.7 seconds left, and No. 2 Purdue edged hobbling Texas star Tramon Mark and the 11th-seeded Longhorns 79-77 on Thursday night in the Sweet 16 of the NCAA Tournament. Texas (21-15) tied it moments earlier when Dailyn Swain made a driving layup, was fouled and converted the three-point play with 11.9 seconds to go. Smith had scored on his own drive with 38 seconds remaining and finished with 16 points. Kaufman-Renn hit his first seven shots on the way to 20 points. He was mobbed by teammates right after the final buzzer sounded at SAP Center.
