Telekom Baskets Bonn hammered Belgacom Liege for their first win in the EuroChallenge Top 16.
Moussa Diagne, averaging just 4.8 points, scored a game-high 22 points to lead Bonn to a 79-64 victory.
Both sides are now 1-2 in Group I.
When Belgacom prepared for the trip to Bonn, they probably didn't take into account the potential damage Diagne could inflict on them.
The Senegalese forward had made just three of 22 shots from long range in the competition but on Wednesday, he drilled four of six from the arc.
Bonn's three-point shooting was a big difference as they made 10 of 20 compared to the Belgian outfit's seven of 18.
Belgacom might have off-set that disparity by making a lot of free throws but they sank only 15 of 23 at the charity stripe.
The game was knotted at 30-30 at half-time.
The spurt that propelled Bonn to victory started with one of Diagne's three-pointers which gave them a 36-32 lead.
Brandon Bowman then added a three-point play after getting fouled while making a jump shot and Ken Johnson dunked to cap the 8-0 run.
The contest was effectively over late in the third quarter after Bonn opened up a 57-38 lead following a Johnson jumper and a lay-up by Winsome Frazier.
Michael Koch's team never let their lead dip below 13 points the rest of the way.
No other Bonn player hit double figures in points while for Belgacom, Will Thomas and Jamar Wilson scored 14 points apiece and Justin Cage 13.
