BK Prostejov rolled to their fifth win in Group E and made sure KK Zagreb failed to win a game in the Regular Season of the EuroChallenge.
Having already secured a place in the Last 16, Prostejov set about making sure their home fans had something to smile about before Christmas and claimed an 86-77 victory.
Kyle Landry finished with 20 points and 14 rebounds for Prostejov.
Mario Kusan had 22 points and seven rebounds in defeat.
Zagreb threatened to pull off an upset in this game.
They only trailed 72-70 midway through the fourth quarter after a three-ball by Damir Rancic.
Benas Veikalas and Radoslaw Hyzy each made two free-throws and Jaromír Bohacík added a jumper to cap a 6-0 run that put the hosts in front to stay.
Prostejov hit 19 of 24 shots from the line and capitalized on 21 Zagreb turnovers - five by Kasun and four by Luka Zoric.
KK Zagreb Head Coach Mladen Erjavec:
"Our biggest problem was the start of the game. We got to a big lose and then it took us about twenty minutes to get back to the game. In the second half, we begun to play good defense and control the ball, it was much better than in the first half. We had the chance to get the game equal, when we shot for 72:72, but we missed and Prostějov scored 4 points. In that time, the game was over."
KK Zagreb player Mario Kasun:
"Like the coach said, the biggest problem was that we opened the game very badly. We lost ten balls in the first quarter and Prostějov took big advantage of that. Then we spent a lot of energy of coming back to the game. But we also made some stupid offenses, like three in a row and at that moment, the game was over."
BK Prostějov Head Coach Peter Bálint:
"As my colleague said, the start was important, we got a quick lead. However, getting a quick lead does not necessarily mean an easy game. The opponent improved their game, stopped losing balls, did less mistakes in defense. Despite these facts, we were always capable of scoring. We controlled the game from the beginning to the end."
BK Prostějov player Kyle Landry:
"Like everybody said, the start was very important to us, we played very well at the beginning. Even when they made their runs, we kept our composure, played strong and always held onto our lead."
