BC "Minsk-2006" put two heavy EuroChallenge defeats behind them and won at Amsterdam on Tuesday in Group C.
Henry Harrison had 17 points as the team from Belarus prevailed, 78-68.
Hammered 106-68 at Krasnye Krylia in their opener and 80-49 at home last week by Scavolini Pesaro, Minsk looked to be headed for a very hard season in Europe.
They faced a 64-56 deficit with 8:29 remaining in the game on Tuesday when the tide turned.
Minsk dug deep and reeled off 16 unanswered points for a 72-64 advantage.
A Harrison dunk and a three-point play by Dzianis Korshuk started the game-winning surge.
Korshuk buried a jump shot and added a three-pointer for a 68-64 Minsk advantage and they pulled away for the victory.
Korshuk and Alexander Fomin each had 16 points for the winners while Robert Krabbendam finished with a game-high 22 points for Amsterdam (0-3).
Jason McCoy, BC Minsk:
"Fortunately we were able to play better in the second half. We started to believe we could win and were able to find the open player for three-point shots."
Andrei Krivonos, BC Minsk Coach:
"We expected a difficult game and I congratulate my team for the improvement in the second half. It was good to see that they managed to find each other on the court and regain their self-confidence. Of course we are very glad with the win."
Ferry Steenmetz, Amsterdam Coach:
"We played well, we were up all game. We came in a situation that instead of making scores inside against their match-up zone we tried to win the game with three-point shots, but they didn't fall. They ran some fast breaks and decided the game in the last three minutes. It was a spectacular game, too bad we don't get points for that. Good experience for the team and we will take this experience to the league."
Dimeo van der Horst, Amsterdam:
"We didn't have the right answer to their zone and therefore were not able to respond when we fell behind."
