The hosts started the game better, running away to a 19-10 advantage after Julius Jucikas and Rokas Giedraitis connected for an alley-oop, capping off a 6-0 run at the end of the first quarter.
Derek Needham, who was orchestrating his team’s game well in the first two quarters, had extended Siauliai’s lead to 28-18, but Prienai cut the gap to 30-23 by the end of the first half.
After a successful start of the third period, TonyBet got within 36-33 after Mindaugas Lukauskis swished in a corner three-pointer, but Travis Leslie responded with a long-range shot of his own on the other end.
The game took an interesting turn when TonyBet’s coach Virginijus Seskus decided to go to a small line-up, playing with Arvydas Siksnius at the center position.
The change of tactics paid dividends instantly, with Siksnius tying the score at 46-all with a long-range attempt before nailing another one to put Prienai up by three.
With a 1:18 left on the clock TonyBet were still leading 57-56, but baskets by Derek Needham and Travis Leslie put Siauliai ahead, while Darius Pakamanis sealed the win from the free-throw line.
