SPOKANE, Wash. (AP) Gonzaga coach Mark Few watched the No. 10 Bulldogs build big leads over Mount St. Mary's in the first half, only to see the visitors claw back into the game.
Gonzaga made it a rout in the second half, outscoring the Mountaineers 60-27 for a 101-56 victory Saturday night.
''We got complacent when we got up by 20, and they kept coming,'' Few said. ''We talked at halftime about not taking our foot off the pedal.''
Domantas Sabonis had 15 points and 14 rebounds and Silas Melson added 15 points for Gonzaga (2-0) in the game that was part of the Battle 4 Atlantis tournament.
BK Ashe had 16 points, and Will Miller 13 for Mount St. Mary's (0-4), which is 1-25 against ranked teams.
Gonzaga struggled early against the Mount's pressure defense, and suffered 14 turnovers in the game. But only two came in the final 19 minutes.
''That was big,'' Few said.
Kyle Dranginis and Eric McClellan each scored 13 points for Gonzaga, while Kyle Wiltjer had 12 points and nine rebounds. Josh Perkins added 11 points.
The Zags shot 62 percent in the second half and finished at 59 percent for the game.
McClellan did a good job of handling the pressure defense of Mount St. Mary's, Few said.
''We are on him to get our energy up,'' Few said. ''He did a really nice job.''
Gonzaga made 11 3-pointers in the game, including 10 in the second half.
The Mountaineers, the preseason favorite to win the Northeast Conference, have opened the season with losses at No. 3 Maryland, Ohio State, Washington and Gonzaga.
''We're striving to be a program like Gonzaga someday,'' Mount St. Mary's coach Jamion Christian said. ''It's been a 20-year process for Gonzaga and we're at the infancy stage of that.''
Christian said his team has shown improvement already this season.
''Down 12 at the half, that's 10 points better than we were a week ago,'' Christian said. ''We've gotten better exponentially this past week.''
Gonzaga held Mount St. Mary's to 35 percent shooting, including just 3 of 21 from 3-point range. The Zags won the rebound battle 49-25.
