Sam Dower Jr. bounced back from one of his worst performances of the season with 15 points and 10 rebounds as part of Gonzaga's 75-47 win over St. Mary's on Saturday.
David Stockton added 10 points, five assists and five rebounds while Przemek Karnowski had 10 points and six rebounds for the Bulldogs (25-6, 15-3 West Coast Conference). Coach Mark Few's team had previously clinched the regular season title and will head into the conference tournament as the top seed.
Dower, limited to six points because of foul trouble in Thursday's win over Pacific, went 7 of 11 from the floor and helped spark an early 21-3 run for Gonzaga.
The Zags led by as much as 34 and outscored the Gaels 42-14 in the paint.
Stephen Holt had 10 points, all on free throws, for St. Mary's (21-10, 11-7).
