WASHINGTON—Making itself right at home on a court that was anything but neutral, Northwestern roared into the semifinal round of the Big Ten Tournament with a 72-64 upset of No. 25 Maryland on Friday night, disappointing an enthusiastic – and biased – crowd.Scottie Lindsey and Vic Law each scored 17 points for the Wildcats (23-10), who took control with a 20-2 run in the second half that all but silenced an arena that earlier produced the loudest cheers of the first Big Ten Tournament held in the nation’s capital.Having already defeated Rutgers and No. 3 seed Maryland, Northwestern on Saturday will face second-seed Wisconsin, a 70-60 winner over Indiana.Though this was technically considered to be a neutral court, Maryland (24-8) enjoyed many of the benefits of playing at home following a double bye to start the tournament.No matter what, the Cats have sewed up their first ever Men’s NCAA hoops birth.
