Alexander scored seven points in OT, including an outburst of five points in 16 seconds to give Creighton (17-13, 8-9 Big East Conference) the lead for good. With the score knotted at 63 in overtime, Krampelj snared the rebound of a Providence miss and Alexander hit a dagger of a 3-pointer from the right corner at the other end.
