Two free throws from Zsofia Fegyverneky extended their advantage to six points early in the second, but Lietuvos then came back as MiZo hit shooting troubles.
With 46 seconds left in the first half, Douglas made a free throw to put Lietuvos 36-35 ahead and they would lead all the way from there.
Douglas' shot was the start of an 11-4 run for Lietuvos which extended into the second half and began to take the game away from the visitors.
