Vincent Mommer's defensive intensity carried RBC Belgrade to a commanding 84–57 victory over St.-Truidense in Group A play. The RBC forward finished with 12 points, 5 rebounds and a game-high 5 steals across 20 minutes, though his shooting touch was inconsistent — he made just 5 of 12 attempts from the field, including 2 of 8 from three. The 27-point margin tells the real story. This was never close, and Mommer's ball-hawking on the perimeter set the tone early. Five steals in a third of the game reflects a team playing suffocating defence, and RBC Belgrade took full advantage of St.-Truidense's struggles to build the kind of cushion that allowed rotation minutes and rest. What stands out is Mommer's efficiency despite the shooting numbers — he was where he needed to be, pressuring the ball and forcing decisions. A single turnover in 20 minutes shows discipline too. RBC Belgrade host their next fixture in Group A with momentum on their side.
