DKV Joventut got 15 points from Spanish international Rudy Fernandez and 12 apiece from Andy Betts and Alex Mumbru as they won convincingly in their EuroCup Group H clash at Gravelines in France, 84-51.
The team from Badalona stormed out to a 21-11 lead and never looked back, stretching their advantage to 43-28 by half-time.
Gravelines did manage to trim the deficit to 12 by the end of the third, but Aloysius Anagonye dunked at the start of the fourth quarter and that was followed by an Andre Turner three-pointer as DKV stamped their authority on the game again.
The Spaniards ended up outscoring Gravelines 25-14 over the final 10 minutes.
DKV finished the game nine of 23 (39%) from three-point range, with Gravelines just two of nine (22.2%).
DKV, one of the leading teams in Spain this season, now have two wins and just one defeat.
They take on Galil Elyon, the side they beat in their opener, next week while winless Gravelines face Dynamo Moscow Region for the second time.
