Otto Porter scored 19 points to lead Georgetown to a 63-47 victory over No. 24 Notre Dame on Monday night, the Fighting Irish's third loss in four games.
It was a dismal night for Notre Dame's offense, which recorded season lows in points scored, field goal percentage (35 percent) and assists (11).
The Irish (15-4, 3-3 Big East) went on long stretches without scoring in both halves, while Georgetown (13-4, 3-3) shot 53 percent from the field.
It was Notre Dame's third Big East home loss over their past 24 conference home games. The game was reminiscent of last season's 59-41 win by Georgetown over the Irish in Washington, when the Hoyas held Notre Dame to its lowest point total in nearly four years by limiting the Irish to 33 percent shooting.
Jerian Grant led Notre Dame with 13 points.
