Luke Harangody had 20 points and 10 rebounds in a healthy performance off the bench, and Notre Dame shut down Seton Hall’s high-octane offense for a 68-56 victory in the second round of the Big East tournament Wednesday night.

Tory Jackson added 13 points and six assists for the Fighting Irish (22-10) in a game with significant NCAA tournament implications. Notre Dame, riding a five-game winning streak, plays second-seeded and No. 16 Pittsburgh in the quarterfinals Thursday night.

The seventh-seeded Fighting Irish improved to 6-14 in the Big East tournament and ended a three-game winning streak for No. 10 seed Seton Hall (19-12).

Harangody, the nation’s second-leading scorer, missed five games with a badly bruised right knee before returning to play 11 minutes Saturday at Marquette. But he looked more like himself in this one.
