Less than 48 hours after their 83-74 defeat to Russian rivals Spartak Moscow Region in the Semi-Finals, Gundars Vetra's team rolled to a decisive win to clinch third place in the competition.
"Everyone knew we came here to win the tournament," Vetra said.
"It was not to be, but I am satisfied with my team's performance today.
"I've got a strong team and we'll keep it going next season."
American Asjha Jones and France international Sandrine Gruda fired UMMC to victory.
Jones led all scorers with 18 points while Gruda poured in 16 and also grabbed a game-high 14 rebounds.
UMMC out-rebounded Sopron 43-30.
Gruda had six points and four boards in the first quarter as Ekaterinburg opened up an 18-9 lead.
She had 10 and six at half-time with Ekaterinburg in command at 37-22.
Vetra's team delivered the knockout punch in the first five minutes of the third quarter and led 49-29.
Sopron, who have an extremely young team with an average age of 21 in the starting line-up, surprised everyone by making it to the Final Four.
"We've had a great EuroLeague Women tournament," Sopron coach Norbert Szekely said.
"In Salamanca, we were not at our best. But I have a young team and this was a great experience for all of them. We will improve, we will get better.
Szekely then had a message for the organizers of the Final Four in Spain.
"Thanks Salamanca," he said. "It's been a fantastic Final Four."
