Gonzaga pushed the lead to 36-14 with just under seven minutes left in the first half, dominating the Lumberjacks in the paint 20-8.
Ayayi had 14 points and nine rebounds at halftime, as the Zags led 51-23.
Northern Arizona was hampered by 22.9% shooting, making just eight of 35 shots. Green had 10 points at the break for the Lumberjacks.
Gonzaga opened the second half with a 14-4 run to take a 65-27 lead with 14 minutes left. The Zags sent in their bench players after that.
Northern Arizona coach Shane Burcar said his team played better in the second half.
“I told our guys in the locker room after the game that there is no such thing as moral victories, but these are big-picture games,” he said. “We don’t want to shy away from any competition, and Gonzaga is really good.
“You play these games to be great in your conference and we look forward to Thursday and Saturday (at Idaho).”
Burcar was particularly happy with Green’s defense on Gonzaga star Corey Kispert.
“He only had eight points and Jay was locked up on him,″ Burcar said.
The Zags were coming off a 98-75 win Saturday over then-No. 16 Virginia in Fort Worth, Texas. That gave them a poll-record four wins over ranked teams in their first seven games. They do not have another currently ranked team on their schedule, and have a good chance to extend their seven-week stay at No. 1. It’s the longest stint in program history.
Few said Suggs hurt his leg in the Virginia game and it started to bother him on the plane ride home. “We’ll see how he does in warmup and make a call tomorrow (on whether he plays against Dixie State),” Few said.
Northern Arizona: The Lumberjacks were coming off their first win of the season at Denver. They are led by Shelton, who averages 19.7 points per game to lead the Big Sky Conference.
Gonzaga: Kispert was selected the West Coast Conference player of the week after scoring 77 points, including a career-high 32 against Virginia, in three victories. That bumped his season average to a team-high 22.4 points per outing. Meanwhile, Suggs was the WCC freshman of the week for the third time. He totaled 39 points, 20 rebounds, 18 assists and eight steals in three games.
Northern Arizona plays at Idaho on Thursday.
Gonzaga hosts Dixie State, which is in its first season of Division I basketball, on Tuesday night. Ayayi said it was silly to think playing back-to-back games is tiring. “We just want to play basketball,” he said.
