France will advance to the quarter-finals of the ACI Trading Ltd U20 European Championship Men in Chekov.
Their 76-57 defeat over a lacklustre Croatia on Sunday gives them the second qualification spot in Group C, ahead of Slovenia and Croatia.
The French closed the first half with an 11-3 run and took a 41-31 lead into halftime, but it was in the third period when they made the game safe.
France's Thomas Larrouquis was the key man in France's scoring burst. The 192 cm shooting guard showed he can put the ball in the basket in the opening game against Russia when he netted 16 points in 15 minutes.
His offensive abilities came to the fore once again against Croatia as he scored 8 points in a 14-0 French run to open the third quarter. The spurt gave France a 58-31 lead at the 27 minute mark and there was no way back for Croatia.
Larrouquis top scored for France with 17 points, while point guard Yannick Bokolo added 15 points, 8 rebounds and 6 assists.
France's win earns them a match-up with title favourites Lithuania on Tuesday in the quarter-final round, while Croatia fail to make the top 8 at the U20 European Championship for the second year in succession.
