Antoine Davis scored 31 points and Justin Miller 17 for Detroit Mercy (2-12), which was playing the nation's top-ranked team for the first time since they lost to Michigan in the 1977 NCAA Tournament in Dick Vitale's last game as the Titans coach.
Gonzaga has won 31 consecutive home games, longest streak in the nation.
Gonzaga came out hot and built a 27-8 lead in the first nine minutes. The Zags got three 3-pointers from Woolridge during the run.
