VILLANOVA, Pa. (AP) -- Alex Rosenberg led Columbia with 21 points as the sharpshooting Lions pulled a 75-57 upset over Villanova on Tuesday night in a nonconference affair.
It marked the first time the Lions (3-1) defeated Villanova (3-2) since a 76-64 victory on Dec. 29, 1969.
Columbia was 7 for 14 from 3-point range in the second half and made its last 21 free throws. Grant Mullins led the charge, going 4 of 4 on 3-point tries after halftime and finishing with 14 points.
Columbia also got 15 points from Steve Frankoski, and Brian Barbour closed the door by going 8 for 8 from the free-throw line in the second half.
Villanova got 13 points from James Bell and 11 from freshman Ryan Arcidiacono.
Columbia went into halftime holding a 26-22 lead, despite shooting 9 for 27 from the floor. The Lions led throughout most of the first half behind nine points from Frankoski.
Villanova didn't help itself. The Wildcats turned the ball over 12 times in the first half, at one point turning the ball over on three straight possessions.
With 5:03 left in the half, a Bell layup gave Villanova a 21-19 lead. But from there, the Wildcats turned the ball over five times and went 1 for 4 from the floor and 1 for 5 from the line on their next nine possessions as Columbia regained the lead.
The Lions went on a 17-5 run after Bell's basket to take control of the game.
