Serbia encountered some problems against a Croatia side still riding high on their win against Germany, but in the end maintained their perfect record with an 84-81 win.
The usual suspects for both sides again put up big numbers.
For the victors, star Milan Macvan led the way again with 21 points and nine rebounds, along with Stefan Stojacic with 21 points and Dusan Katnic with 15.
Milan Macvan had another big game for Serbia with 21 points to go with nine rebounds.
For Croatia Filip Kruslin had yet another good day with 20 points, followed by Mario Delas with 17 points and six boards and Marino Sarlija with 16 points.
The crowd were again out in force in support of Croatia, helping them off to great start.
They were too fast for Serbia on some good breaks in the opening minutes and soon ran up a comfortable looking early lead.
After good performances against Macvan and Stojacic were being kept under wraps by a spirited Croatia, as Serbia looked uncomfortable shooting from beyond the arc missing every one of nine attempts.
In the second Serbia hit their first trey of the game through Nikola Markovic during an 8-0 run at the start of the quarter which turned the game into a contest.
They finally took the lead for the first time with 3:38 remaining after Macvan converted a two pointer whilst forcing the foul, taking the score to 34-31.
The three point gap remained at the start of third, but with Macvan and Stojacic now off the reins Serbia ran it out to 14 points with 3:34 remaining in the quarter.
But a determined and well organized Croatia gradually came back into it, giving away no fouls until 1:12 remaining in the fourth and with Delas, Kruslin and Karlo Vragovic all scoring well to pull the game to within three points with 37 seconds left and Serbia with the ball.
But when the fouls did come they cost Croatia dearly.
With three seconds left and against deafening noise from the crowd Macvan converted his second free throw to give his side an unassailable 84-80 lead.
A relieved Macvan said after the game that his side had had to fight hard to get this fourth win.
“That was very difficult, really very difficult for us. Croatia are a good team”.
“We had a bad first quarter, but we got control again in the third. For me this was so difficult because they had their five guys always on rotation so they were always all over me” he concluded.
The win puts Serbia in a strong position to reach the semis, whilst really leaving Croatia up against it to make the higher positions.
