SAN FRANCISCO — Darrion Williams scored the tiebreaking basket with 7.3 seconds left in overtime after tying the game with a 3-pointer in the closing seconds of regulation to lead Texas Tech to an 85-83 win over Arkansas on Thursday night and a spot in the Elite Eight.

The first overtime game of March Madness came thanks to a furious comeback by the third-seeded Red Raiders (28-8) from 16 points down midway through the second half against coach John Calipari’s 10th-seeded Razorbacks (22-14).

Texas Tech advanced to play top-seeded Florida in the West Region final on Saturday.
