Saint Mary's scored eight of the next 10 points to pull within five but got no closer. The Gaels went scoreless over the final six minutes, 17 seconds of the game.

Sam Simons had 16 points, including four 3-pointers, and Sydney Raggio scored 11 with 16 rebounds for Saint Mary's (14-8, 7-4), which had its five-game win streak snapped. The Gaels, who were held to their lowest scoring output of the season, committed 21 turnovers. They came in ranked No. 1 in the conference in scoring (77.7 points per game), 3-point percentage (.390, eighth nationally) and field-goal percentage (.492, ninth) but shot just 4 of 22 (18 percent) from 3-point range and shot just 32.7 percent (18 of 55) overall.
