SOUTH BEND -- Luke Harangody scored 20 points and No. 19 Notre Dame beat St. John's 68-55 on Wednesday night to become the first Big East team to go undefeated at home in conference play in consecutive seasons.
The Fighting Irish (23-6, 13-4) opened a 10-point lead late in the first half and kept it in double digits most of the rest of the way. Kyle McAlarney, who finished with 13 points, hit a 17-foot jumper with 1:13 left to extend the lead to 68-50.
The Irish, who shot 54 percent from the field, extended their Big East home winning streak to 18, two shy of tying the league record set by Pittsburgh over three seasons, ending in 2004. The Irish extended their overall home winning streak to 37 games, one shy of matching the school record set from 1943-48.
Anthony Mason had 16 points for the Red Storm (11-18, 5-12), who dropped their 22nd straight road game to a ranked team dating to 2002. St. John's needs to win its final home game against West Virginia on Saturday and for DePaul to lose at Cincinnati and Pittsburgh to qualify for the Big East tournament.
St. John's managed to hold the Irish, who entered the game averaging 81.6 points a game, under 69 points for just the fifth time this season. But the Red Storm couldn't generate enough offense to stay competitive, shooting 41 percent.
St. John's cut the lead to 33-25 early in the first half when D.J. Kennedy scored inside. But the Irish regained control immediately when Rob Kurz converted on a three-point play and McAlarney hit a 3.
Harangody was 9-of-12 from the field and had six rebounds. Harangody scored six points during an 8-0 run that opened a 29-17 lead with 4:45 left in the first half.
Kurz added 15 points for the Irish, who outscored St. John's 36-28 inside and 20-7 off turnovers.
