No. 3 North Carolina (13-1) @ No. 1 Northwestern (12-0)
Friday, 7 p.m.
Outlook: Defending national champion Northwestern has won 21 straight games and is beating teams by an average of 8.6 goals, but the Wildcats have had a couple of close calls, needing overtime to dispense with then-No. 2 Syracuse and then-No. 13 Ohio State. The Tar Heels have that same upset potential. Although they're well behind in the series, 8-2, the Heels pushed the Wildcats to overtime last season before falling, 7-6. Both teams have played nine ranked opponents, with North Carolina's only loss coming in overtime.Copyright © 2015, The Baltimore Sun
