Tyreke Key scored 12 points, Jahmai Mashack added 11 and No. 4 seed Tennessee survived a late scare to hold off Louisiana-Lafayette 58-55 in the opening round of the NCAA Tournament on Thursday night.

The Ragin’ Cajuns (26-8) whittled an 18-point deficit to three in the final minute — creating some tense moments and a couple technical fouls — but the Volunteers (24-10) closed it out by forcing tough shots and making just enough free throws.

Tennessee, which lost six of 10 heading into the tournament, advanced to face fifth-seeded Duke in the East Region’s second round at the Amway Center.
