UNCASVILLE, Conn. — Top-ranked UConn has become known for that one big run that puts opponents away.
Monday night’s was bigger than most.
The Huskies outscored Cincinnati, 38-0, over 15 minutes that stretched from the first quarter into the third and went on to rout the Bearcats, 75-21, in the semifinals of the American Athletic Conference tournament.
Azura Stevens scored 21 points and pulled down 13 rebounds and Napheesa Collier added 13 points for the Huskies (31-0), who have won 100 games against AAC opponents without a loss since the league began play in 2013.
UConn has won its last 157 games against unranked opponents and has 332 wins in its last 333 games against those outside the Top 25.
‘‘We’ve had some runs against some really good teams that you can’t explain,’’ said UConn coach Geno Auriemma. ‘‘Maybe because we play pretty good defense every night, we get a lot of opportunities to get out in transition. That’s the only way I can explain it.’’
Andeija Puckett had 5 points for Cincinnati, which fell to 19-12.
The Huskies play South Florida in the AAC championship game at 5 p.m. Tuesday. This will be the fourth straight time the teams have met for the title. UConn won the previous three by an average of 32 points.
USF coach Jose Fernandez didn’t keep his team around after their victory over UCF to watch UConn’s win.
‘‘They don’t need to watch them any longer,’’ he said. ‘‘They’re on TV all the time.’’
The Huskies played Monday without All-America forward Gabby Williams, who tweaked a long-standing hip injury in the Huskies’ quarterfinal win over Tulane.
They didn’t need her.
The Huskies led just 9-5 after a 3-pointer by Cincinnati’s Nikira Goings with 4:39 left in the first quarter. Those would be the last points the Bearcats would score until just over a minute and a half into the second half.
UConn scored the final 8 points of the first quarter and outscored Cincinnati, 26-0, in the second to take a 43-5 halftime lead.
The Bearcats, who had won six of their previous seven games, shot 14 percent, making just eight baskets on 58 attempts.
‘‘Our goal is to always shut teams out, but that very rarely happens’’ said Collier. ‘‘We did notice [the run] especially toward the end and right into halftime, but during the game we’re kind of locked in on defense and trying to do what you need to do instead of looking up at the score.’’
The 5 first-half points tied for the fewest the Huskies have ever given up in one half. Fairleigh Dickinson scored 5 against UConn in November, 2011.
Shanice Johnson ended the Bearcat drought with a 3-pointer that made it 47-8. UConn continued to stretch the lead, going up by as many as 56 points.
Stevens, starting in place of Williams, had her seventh double-double by intermission, with 14 points and 11 rebounds. It was the 6-foot-6-inch junior’s eighth start since transferring from Duke. But the AAC’s sixth player of the year said her approach was no different than when she comes off the bench.
‘‘My role changed a little bit tonight, but not really,’’ she said. ‘‘I’m still expected to do what I’m expected to do every night and I think as a team we did a good job pulling together a solid win for Gabby.’’
