Notre Dame didn't wait until the second half to get going as it has so many times this season.
The Irish took a 45-22 lead into halftime over IUPUI on Wednesday in Purcell Pavilion. The 23-point lead is the largest for Notre Dame after the first half since holding a 31-point edge over North Florida in an 86-65, season-opening win Nov. 14.
After surrendering the first two points of the game on free throws to the Jaguars, the Irish took over building an 11-2 lead 3 minutes into the game.
IUPUI was able to pull within 19-14 with 12:48 to play in the half, but Notre Dame went on another game-controlling run.
The Irish outscored the Jaguars 14-3 over the next 5 ½ minutes to take a 33-17 lead.
Notre Dame shot 53.1 percent in the first half and connected on 40 percent of its three-pointers.
Irish guard Ben Hansbrough went 5 of 6 from the floor, including 3 of 4 on three-pointers, for 15 points. Forward Luke Harangody scored 11, and forward Tim Abromaitis added 10.
Notre Dame held IUPUI to 25.9 percent shooting and turned eight Jaguar turnovers into 15 points. The Irish also held a 21-16 rebounding edge and scored 20 points in the paint compared to the Jaguars' 6.
