SOUTH BEND, Ind. -- Skylar Diggins scored 18 points, Natalie Achonwa had 16 points and 12 rebounds for her 10th double-double of the season and No. 2 Notre Dame beat 74-50 St. John's on Sunday.
The All-American penetrated at will. When she wasn't scoring on fast breaks, she was hitting pull-up jumpers or feeding forward Achonwa for easy layups.
