The memory of Rivas Ecopolis' five-game winning streak in the EuroLeague Women is fading fast with Good Angels Kosice on Thursday sending the Spanish club to its second consecutive defeat in the competition.
Erin Lawless poured in 20 points for Kosice in their 68-62 triumph.
Kosice beat Rivas for the second time this season and now both sides have 5-4 records in Group C.
The visitors from Slovakia led 41-32 midway through the third quarter but weren't able to press home the advantage with Rivas pulling level by the end of the frame at 47-47 after eight straight points by Jelena Dubljevic.
Laura Nicholls and Anna Cruz then began the fourth quarter with baskets and Rivas had the perfect platform for victory.
But down 56-51 with 4:38 to play after a three-ball by Rivas guard Elisa Aguilar, the visitors regained control of the game.
Danielle Mc Cray scored six unanswered points - four of them from the stripe - for a 57-56 lead.
Lawless followed with a jumper and after Natalia Vieru split a pair of free-throws, Lawless struck from behind the arc for a 63-56 advantage.
Rivas called a timeout but failed to come up with an answer to Kosice's excellent play.
Asjha Jones had 14 points and 11 rebounds in defeat.
