Cedi Osman poured in 28 points or Turkey to go along with 7 rebounds, 7 steals and 4 assists. A basket by Sinan Guler of Fenerbahce Dogus Istanbul had put Turkey up 13-10 in the first quarter, but Russia scored the next 10 points to take a lead that held, despite one tie after halftime, until early in the fourth quarter. That's when Guler's layup with 7:55 left made it 58-57 but Shved answered for Russia, which stayed in front. Guler's alley-oop to Furkan Korkmaz and Cedi Osman's bank shot put Turkey ahead again 68-66 with 3:36 to play.
