In what had been a tight contest, Wisla found themselves trailing until Janell Burse's free-throw tied it at 55-55 with 4:54 to go, but Katerina Zohnova's three-pointer then fuelled a 15-2 Wisla run to finish the game.
Marta Fernandez led the victors with 17 points, while Zohnova finished with 13 and Liron Cohen and Ewelina Kobryn had 12 each. Burse grabbed 16 rebounds to go with seven points.
Mizo got 18 points from Anna Vajda, while Nicole Ohlde chipped in with 11 and Alexandria Quigley had 10.
Ákos Füzy, Mizo Pecs 2010 coach:
"It was a very good game and the fans of both clubs have been fantastic. The game was very difficult for both teams and the details decided the winner. I want to thank my players for two very good games, the previous one in Pecs and now in Krakow. They should help us become a better team to fight for honours in the Hungarian League and Cup. Congratulations to Wisla, I wish them to get to the Final Four."
Jose Hernadez, Wisla Can-Pack coach:
"I am very happy; we need to win two more games to get to the Final Four! Let us dream that dream of EuroLeague as long as possible. Many thanks to my players and to the fantastic fans that were our sixth player today. I wish the Pecs Team all the best for the rest of their season."
