DAYTON, Ohio -- Ole Miss pulled off the NCAA tournament's first big comeback.

Against the team that's known for the biggest one of all, no less.

Stefan Moody scored 26 points and led Mississippi's comeback from a 17-point halftime deficit to a 94-90 victory over BYU on Tuesday night in the First Four.

The Rebels (21-12) trailed until Moody led a 15-2 run midway through the second half. He hit a late 3-pointer that helped finish it off.

"Welcome to March Madness!" Mississippi coach Andy Kennedy said.

It was some way to get it going.

Ole Miss goes to Jacksonville, Florida, to play sixth-seeded Xavier on Thursday afternoon in the East Region, a team that Kennedy knows well from his days as a coach at Cincinnati.

BYU (25-10) pulled off the biggest comeback in NCAA tournament history in Dayton three years ago, rallying from a 25-point first-half deficit to a 78-72 win over Iona in the First Four. This time, the Cougars couldn't hold the big lead.

"This game will sting for quite a while," coach Dave Rose said. "It was pretty similar to (three) years ago when we were here."

Tyler Haws, a senior guard who is BYU's all-time leading scorer, had 33 points but missed a 3-pointer as BYU tried to catch up in the closing seconds. It was the first time this season that the Cougars lost after leading by 17 points.

A Tale of Two Halves For Ole Miss Ole Miss was a different team in the second half, nearly doubling their scoring output and only turning the ball over three times: 1st Half 2nd Half Points 32 62 FG 12-40 24-40 3-pt FG 3-12 4-11 Turnovers 4 3

"We did enough offensively to win the game," Haws said. "We found our rhythm in the first half and got it going. It got away from us in the second half. We didn't really have any answers for them defensively."

Haws had 19 points in the first half, helping the Cougars pull ahead 49-32. Moody got the Rebels' guard-driven offense going midway through the second half, when three BYU players picked up their fourth fouls and things opened up near the basket.

"Definitely a sense of urgency," said Moody, whose 26 points were an Ole Miss NCAA tournament record. "We could have went in the locker room, sulked about it and come back out, and it would have just got worse."

M.J. Rhett added a career-high 20 points for Ole Miss, including a pair of three-point plays and a dunk during the go-ahead run.

Chase Fischer put the Cougars ahead 8-0, making a reverse layup and a pair of 3s. Ole Miss missed 15 of its first 19 shots overall as BYU took control. Fischer finished with 23 points, going 6 of 12 from beyond the arc.
