Under Ryan Fieldhouse’s blinding lights, the No. 4 Northwestern squad shone bright, defeating Marquette and returning to the victory column. The 21-3 win comes after the Wildcats (2-1, 0-0 Big Ten) snapped their 22-game win streak against then-No. 8 Notre Dame last week. For coach Kelly Amonte Hiller, the key to Monday’s success was key.
