In its first defeat of the season, Adonis Filer was the lone player for Clemson (2-1) in double figures. He finished with 10 points for the Tigers, who will take on Utep on Friday.
The two teams played a tight first half, with Clemson carrying a 24-23 advantage into the final 20 minutes, but the Bulldogs took a 29-27 lead following a pair of Olynyk free throws.
Harris then capped an 8-0 spurt for Gonzaga with a layup to put the Bulldogs ahead, 47-39, and Dower's bucket a minute later saw their lead balloon to double-digits.
Filer buried a 3-pointer with 1:37 left to play to pull the Tigers within seven, but they never got any closer, as Dower connected on 3-of-4 free throws from that point on to seal the win.
The Bulldogs shot 70 percent from the field in the second half ... Gonzaga improved to 2-0 all-time against Clemson.
