The Pipers won the team competition, 178.675-172.950.
Weniger scored a personal best 37.775 points (vault - 9.525, uneven bars - 9.350, beam - 9.275, floor - 9.625) en route to winning the all-around title in Walker Fieldhouse.
The all-around victory was Weniger's second in as many meets.
Her score on vault was also a personal best and she won the vault, bars, and floor exercise titles.
The Pipers swept the top three spots on both the balance beam and floor exercise. Brynn Stenslie (Sr., Renton, Wash.) beat out Weniger on the balance beam to prevent the individual event sweep by her teammate. Weniger finished second on that apparatus, and Molly Weber (So., Taos, N.M.) was third with a 9.225.
Weniger won the floor, followed by Sarah Prosen (So., Apple Valley, Minn.) in second with a 9.500 and then Stenslie in third with a 9.400.
Prosen also finished third on the vault with a 9.350. Alisha Anderson (Sr., Spring Lake Park, Minn.) finished second on the uneven bars.
The Pipers will next compete in the Best of Minnesota meet featuring Hamline, Gustavus, Winona State, and the University of Minnesota. The Gophers will host the meet at 6:00 p.m. on Saturday, February 14.
