NASHVILLE, Tenn. — Sean Pedulla sank a long 3-pointer with 1.3 seconds left after two missed two free throws at the other end to give No. 8 seed Mississippi an 83-80 victory over ninth-seeded Arkansas in the second round of the SEC Tournament. Arkansas forward Trevon Brazile was at the free-throw line with 7.4 seconds left after he was fouled going for an offensive rebound. He missed both free throws and Dre Davis grabbed the defensive rebound. Davis passed it ahead to Pedulla, who dribbled up the court for a shot well behind the arc for a go-ahead 3-pointer.
