Rima Valentiene, having missed her only shot from behind the arc through three quarters, connected on all four of her attempts in the final 10 minutes and Iveta Marcauskaite also made both of her long-range shots.
If they had not been on target, Nevriye Yilmaz would have gained all the plaudits because she scored 12 of her 20 points in the final quarter in a terrific performance after missing two games with a back injury.
The Czech Republic edged Belgium 72-70, sending Ann Wauters and Co to a second consecutive narrow defeat.
The result has left the Czechs top of Group E, with Belgium slipping to third behind Latvia.
Latvia capped off their Group E qualifying round campaign with a 60-47 victory over Germany.
