Kendall Pollard scored 17 points, and Dayton used every bit of its home-court advantage on Wednesday night, rallying for a 56-55 win over Boise State in the First Four.
The Flyers (26-8) will play sixth-seeded Providence on Friday in Columbus, Ohio.
It was the first time since 1987 that a school has played an NCAA Tournament game on its home court, an anomaly resulting from Dayton hosting the opening games. The Flyers went 16-0 at home during the regular season and have won 22 straight at UD Arena, seventh-longest active streak in Division I.
The Flyers trailed by as many as 12 points in the first half and by seven with 3:43 to go. With the crowd of 12,592 behind them — the biggest attendance for a First Four game — Dayton closed with a 10-2 run.
Derrick Marks' leaning 3-pointer at the buzzer was far off the mark, finishing it off. Marks had 23 points on 10-of-21 shooting.
The Broncos had already snapped San Diego State's 29-game home-court streak this season, and came up just short of another big road win. The Broncos missed seven of their last eight shots.
Jordan Sibert's two free throws tied it at 53-53 with 1:02 left, and his long 3-pointer gave the Flyers a 56-55 lead with 34 seconds to go.
After Montigo Alford missed a driving bank shot, and Pollard got the rebound, was fouled and missed both free throws with 14 seconds left, giving the Broncos a final shot. Marks leaned into Kyle Davis on the final attempt, which missed everything.
Marks, the Mountain West Player of the Year, was coming off one of his worst shooting games during a 71-66 overtime loss to Wyoming in the conference tournament. He kept the Broncos ahead most of the way.
Marks had a 3-pointer and a pair of driving layups during a 14-0 run that put Boise State ahead 29-17 late in the first half. With Sibert on the bench with three fouls, the Flyers couldn't generate points.
The senior guard returned for the second half, and Dayton made seven of its first eight shots to take the lead. Scoochie Smith's back-to-back 3s put the Flyers up 37-34.
The Broncos responded with a 13-1 run led by Marks. Also, Sibert picked up his fourth foul during the spurt, allowing Boise State to stay ahead until the end.
Dayton is 18-17 overall, including 1-1 at UD Arena. The Flyers also lost a tournament game to Villanova at UD Arena in 1985.
Boise State is 0-7 all-time. The Broncos also were sent to the First Four in 2013 and lost to La Salle 80-71.
Dayton: The Flyers wore something other than their white jerseys at home for the first time since 2010, when they added a black jersey. Technically, they were the visitors on their home court.
Boise State: During the season, the Broncos made an average 8.8 3-pointers per game, which ranked 16th in Division I. They went only 6 of 20 against the Flyers.
Dayton: The Flyers will play sixth-seeded Providence on Friday in Columbus, Ohio.
