Cras Basket Taranto wrapped up first place in EuroLeague Women Group A on Wednesday night with a heart-stopping triumph at Wisla Can-Pack Krakow.
France international Elodie Godin had 14 points - including a go-ahead jumper with 35 seconds remaining - to lift Taranto (7-1) to a 58-57 win.
Erin Phillips had a chance to put Wisla back in front after Godin's basket but missed.
Jose Ignacio Hernandez's side now have a fight on their hands to lock up second place as they are level with Good Angels Kosice at 5-3 with two games remaining.
After the next game at TTT Riga, Wisla will head south to Slovakia to face Good Angels in a contest that could decide which team finishes runner-up to Taranto.
Taranto had to dig deep to win this one.
With 5:30 to go, they were staring at a 53-46 deficit after a Phillips jump shot.
Baskets from Sara Giauro, Michelle Greco and Brooke Smith cut the home side's lead to 53-52 with 3:47 to go.
Australia international Phillips scored, taking her points haul to 18, but Greco replied with a jumper for Taranto and then passed to Godin, who struck to put her team in front at 56-55.
Dorota Gburczyk-Sikora gave Wisla their last advantage at 57-56 with 43 seconds to go.
Godin scored for the second straight trip down the floor and it proved to be the game-winner.
Roberto Ricchini, Cras Basket Taranto coach:
"I am very happy and proud of my team. We knew it would be hard and we have respect for Wisla Krakow."
Jose Hernandez, Wisla Can-Pack coach:
"I am sorry. We lost and it is mine and my players' responsibility. We cannot make such stupid turnovers. They should not even think that, they are professionals. We have time now [ahead of us] to think and analyze all that happened. Congratulations to the Taranto team."
