After Ty Berry went 1 of 2 at the free-throw line with 5.8 remaining to give Northwestern a 79-77 lead, Iowa got it past midcourt before calling a timeout with 0.8 seconds left. Brock Harding struggled to find an open teammate from the sideline before Dix came out well past the 3-point arc to swish a fade-away 3-pointer.

Dix's teammates raced to surrounded him at the other end in front of the Northwestern bench, with fans coming onto the court in celebration.

Northwestern rallied in the second half to take a 74-68 lead with 2:15 left.

Barnhizer worked down the clock before getting fouled on a drive with 21.7 seconds left. He made two free throws to give Northwestern a 78-75 lead. Harding made a layup at the other end while being fouled but he missed a free throw that would have tied it.
