Rivas Ecopolis stunned Halcon Avenida and Ros Casares last weekend to win the Copa del Rey for the first time in their history.
Riding that momentum of those great wins, Javier Fort's side thrashed Gospic Croatia on Thursday night for their fourth victory in EuroLeague Women B.
DeWanna Bonner, the MVP of the Copa for Rivas, had 22 points and eight rebounds in the rout of Gospic.
If Rivas win at Lotos Gdynia next week and MKB Euroleasing Sopron (also 4-5) fall at Gospic, Rivas will go into the play-offs as the third-place team in the group.
Rivas, who also got 16 points from Amaya Valdemoro and 12 from Courtney Paris, out-rebounded Gospic 33-23.
Laura Nicholls continued her fine play of late with nine points and five rebounds in less than 15 minutes for the Spanish club.
