Szeviép have taken the inside track to a fourth-place finish in Group D with a 71-58 victory over Lotos Gdynia.
The victory was the Hungarian club's second in the competition, with Gdynia and Tarbes also sitting on two wins apiece.
If the three sides were to finish with two wins apiece, Szeviép would clinch fourth and the last play-off place on goal differential.
Beaten 74-61 at Lotos in the first meeting between the sides in November, a Magdalena Leciejewska lay-up for the Polish team left Szeviép trailing 33-30 at half-time.
On top 45-42 with 1:35 to go in the third quarter, Szeviép outscored the visitors 15-2 over the next five minutes to take command for good.
Olena Zherzherunova finished with 21 points, eight rebounds and four assists for the winners.
Ivana Matovic scored 13 points, hauled in eight rebounds and dished out five assists in defeat.
Jacek Winnicki, Head Coach Gdynia:
"We started bad, but after that we had quite good second quarter. In the third quarter we shot unbelievably badly and made lots of turnovers. Now we've got a very slim chance of winning against Brno. We'll try."
Alana Beard, Gdynia:
"We couldn't put the ball to the basket at all. It's a huge disappointment, we almost lost our chanches to qualify to the next round."
Tamás Bencze, Head Coach Szeviép-Szeged:
"We put a lot of work into this game. I can mention each of my players, everybody gave her best today. Now I really feel sorry about losing at Tarbes."
Vaida Sipaviciute, Szeviép-Szeged:
"We knew we must win today. And we did it. We made a very good teamwork today. I feel happy."
