DeLisha Milton was the stellar performer for Ros Casares with a double-double as US Valenciennes Olympic were beaten 76-69 in EuroLeague Women Group C.
The 32-year-old center poured in 26 points and grabbed 10 boards as the visitors from Valencia extended their record to 4-2 and boosted their hopes of finishing topof the group.
The American was ably assisted by Elena Tornikidou, the forward who added 10 points and five rebounds.
Ros managed to create a 14-point lead (72-58) with 3:27 to go and although USVO were able to close the gap slightly in the latter stages, they could not complete their recovery.
The hosts could at least boast having the top scorer on the night - Sandrine Gruda (27 points) - while Kristi Harrower added a further 20.
They now have a 1-5 record and are in danger of missing out on a top-five finish in the group.
