Serbia & Montenegro have bounced back following their opening defeat by winning consecutive games after Sunday's 63-50 triumph over Romania in Izmir.
An upset looked to be on the cards when Romania went on a 19-3 run to lead 41-38 with a minute to go in the third quarter.
Guards Annemarie Parau and Ildiko Vass had been the inspiration in that spurt.
However, they were unable to keep the momentum going for the rest of the contest.
Their undoing came in the last three minutes when Serbia & Montenegro outscored them 11-0.
Monika Veselovski led Serbia & Montenegro with 15 points while Vass had a game-high of 19 points and seven rebounds in defeat.
Serbia & Montenegro did a lot of damage from the free throw line, making 18 of 28 free-throws, many of them late in the fourth quarter.
