An 18-7 run late in the second half erased a seven point deficit and gave Southern Illinois a lead en route to a 74-64 win over Duquesne.
The loss ended the Dukes seven-game winning streak, their longest since 2010.

Southern Illinois led by three at the half but a strong start to the second half eventually gave Keith Dambrot’s team a seven-point lead.
With 1:40 left, Tarin Smith made two free throws to get within one but Southern Illinois scored the last nine points, including seven on free throws.
The big problem for the Dukes was that aside from Smith, the rest of the team went cold. Smith scored a career-high 26 points but the rest of the team shot just 26% (11 of 42) from the field.
Aside from Smith, only two Dukes reached double-digits in scoring: Duquesne’s leading scorer Mike Lewis had 10 points while Eric Williams had 13 points and seven rebounds.
For the game, Duquesne was able to connect on only three three-point shots.
The Dukes finish their non-conference record with a 9-4 record. Next up is the A-10 opener on Saturday at home against Dayton.
