Jordair Jett matched his career best with 19 points and Saint Louis pressured No. 9 Butler into a season-worst 23 turnovers, recording the program's biggest upset in nine years with a 75-58 victory Thursday night that had fans storming the court to celebrate.
Dwayne Evans added 15 points on 6-for-8 shooting and five rebounds for the Billikens (15-5, 4-2 Atlantic-10), who fed off just the fourth sellout at 5-year-old Chaifetz Arena and led by double digits most of the game. Saint Louis shot 50 percent.
Rotnei Clarke had 17 points for Butler (17-4, 4-2) but also had five turnovers. Andrew Smith added 12 points and six rebounds.
Butler is the highest-ranked opponent to play at Saint Louis, led by interim coach Jim Crews with a roster assembled by the late Rick Majerus, since No. 2 North Carolina in 2006-07.
