» GAME STORY: Turnovers, foul trouble among Dayton's issues
Xeyrius Williams scored three points off the bench for Dayton. Kostas Antetokounmpo scored two. Each had three rebounds. Antetokounmpo had four fouls in 11 minutes.
The other two reserves, John Crosby and Matej Svoboda, combined for three turnovers, no points and one shot attempt. Crosby played only two minutes. Svoboda played nine.
Saint Louis sophomore forward Jalen Johnson, who started the first 15 games of the season, scored 16 points off the bench for the Billikens.
"It speaks for itself tonight," Dayton coach Anthony Grant said. "You look at the box score, and you see off the bench 21-5. We knew Johnson was a very capable shooter."
Crowd size: Saint Louis drew its biggest crowd of the season (8,552). It averaged 5,874 in the first 13 home games.
All the fans at the game received white T-shirts on their seats. One section of the white-out crowd — the students who hang over the tunnel used by Dayton to enter and leave the court — got in the faces of the Flyers as they walked to the locker room at halftime. Dayton's coaches had to ask security guards for help, and at least one student was removed from the stands.

Saint Louis players celebrated the victory, their first over Dayton since 2014, by going into the stands with the students after the game.
"That was a great crowd today," Saint Louis coach Travis Ford said. "At 3 o'clock on a Saturday afternoon, you can choose to be at a lot of places. There are a lot of malls around here. There's a lot of games on TV. That you chose at 3 o'clock to be with us, to be a part of the white-out, to support this team — I don't say it lightly — it means a lot. These are some good kids. They're fighting hard."
