Ros called a timeout and when play resumed, Moore ended up hitting a jumper with 36 seconds to play to make it 68-61 - the final score.
Joens had 17 points in defeat for Bourges.
Ros Casares head coach Roberto Íñiguez
"We know that we won't win all games with 40 points difference. These games are more important because the team had to suffer to win today and we learn from this experience."
Bourges Basket head coach Valérie Garnier
"This was a good game for us. We lost our pointguard, Celine Dumerc, and it was a difficult game at the beginning and without her it's more difficult but I think the team did a good job."
Ros Casares player Maya Moore
"They play a hard game and we had to focus for 40 minutes. In the second quarter we played very good defense, they only could score six points."
Bourges Basket forward Endene Miyem
"It was a really tough game. We did our best and we're a little bit disappointed because at the end score was so close and Ros Casares is a really good team. We are proud of what we did tonight."
