PARADISE ISLAND, Bahamas -- Andrew Wiggins scored 12 of his 17 points in the second half, and No. 2 Kansas moved into the semifinals of the Battle 4 Atlantis, downing previously unbeaten Wake Forest 87-78 on Thursday.
Kansas will play Villanova on Friday night for a spot in the title game.
Codi Miller-McIntyre scored 20 of his 26 points in the second half for Wake Forest (5-1). The Demon Deacons held Kansas to a season-low 47 percent from the field but lost forward Devin Thomas after he was ejected for two technical fouls with 7:28 remaining.
When Thomas got ejected, Kansas' Conner Frankamp made three of the four free throws to put the Jayhawks up 64-52. And when Wiggins, who was largely silent offensively for the first 35 minutes, made a 3-pointer for a 68-57 lead, the overwhelmingly pro-KU crowd might have sensed that Wake's upset bid had run dry.
The Demon Deacons had other ideas.
Miller-McIntyre kept attacking, and his 3-pointer with just less than two minutes left got Wake Forest within 77-72. Desperately needing a stop, Wake Forest wound up losing Arnaud-William Adala Moto to his fifth foul when he got in Wiggins' way on a drive with 38 seconds left.
Wiggins made the first free throw and missed the second, but the ball bounced out of bounds to Kansas. Naadir Tharpe hit a pair of foul shots to make it a three-possession game, and Kansas escaped.
A three-games-in-three-days tournament is a chance for teams to show off their depth.
Kansas wasted no time in doing just that.
The Jayhawks had eight players score in the first 10 minutes, running out to a quick 24-13 lead. A 17-2 run put Kansas in control early, with the Demon Deacons getting only one field goal in a stretch that lasted nearly eight minutes.
Kansas had seven players score in that burst, with no one getting more than four points and Wiggins not even registering a field goal.
Wake Forest weathered that storm and had the game within 27-20 with 5:25 left until the break. That's when the Jayhawks hit the gas again, scoring 13 of the next 17 points before winding up with a 40-26 edge at intermission.
Miller-McIntyre got a layup to fall just before the halftime buzzer, and perhaps that gave Wake Forest some momentum.
The Demon Deacons opened the second half on a 16-6 run, getting within 46-42 when Miller-McIntyre appeared to lose the ball as he elevated toward the rim but getting the shot to fall anyway. Kansas even botched alley-oop passes on consecutive possessions, one bouncing off the rim and another sailing out of bounds.
Still, the Jayhawks never lost the lead in the second half.
Kansas survived a scare late in the half when Andrew White III was fouled under the basket by Wake Forest's Travis McKie and stayed down for a few moments after a hard landing. White eventually got up, made one of the two awarded free throws and stayed in the game.
