The first-half scoring was the second-lowest of the season for Notre Dame, which shot just 32.1 percent (9 for 28) overall and 1 for 10 on 3-pointers before halftime. The Irish scored 20 in a 69-58 loss to then-No. 18 Indiana on Dec. 17.
Parker, scoreless in 14 minutes in the first half after setting a career-high with 21 points in Cincinnati's 66-63 win at then No. 22 Pittsburgh on Sunday, made three 3-pointers in the first 2 1/2 minutes of the second half to help the Bearcats open up a game-high 17-point lead, 43-26. Notre Dame got no closer than eight points.
