Jalen Avery and Jaylin Walker scored 18 points apiece and combined for 7 of 9 3-pointers for Kent State (16-5, 5-3 Mid-American Conference), who were outrebounded 41-33 but forced 20 Cardinals turnovers. Williamson and Phil Whittington added 13 points apiece and Williams had eight with four steals.

K.J. Walton scored a career-high 26 points for his fifth 20-point game of the season for the Cardinals (11-11, 2-7). Tayler Persons scored 14 points with seven rebounds and Tahjai Teague added 14 points before fouling out.
