Russia rebounded from Tuesday's defeat to Slovakia by beating the Czech Republic 78-60 at the UMCOR U18 European Championship for Women.
The Czechs had led through the first four minutes of the second half before the wheels came off.
Russia scored 25 of the next 27 points, an explosion that didn't end until the fourth quarter, and Romana Ptackova's Czechs never recovered.
Russian center Natalia Vieru had a game-high 33 points and corralled 11 rebounds while team-mate Tatitana Petrushina poured in 20.
The Czechs led 25-15 12 minutes into the game. Russia tied the game at the start of the third quarter and eventually blew away their opponents.
They enjoyed their biggest lead at 76-52 and outrebounded their opponents 58-32.
