Reliable soccer-ball detection is a key building block for sports analytics, broadcast enhancement, and robotic training systems, yet it remains challenging because the ball often occupies a very small region and appears under motion blur, occlusion, and complex backgrounds. This paper presents YOLO-P1P2-CBAM, a lightweight modification of an Ultralytics YOLO11 detector that (i) adds extra high-resolution detection heads (P1 and P2) to better preserve fine spatial details for tiny targets and (ii) injects Convolutional Block Attention Modules (CBAM) to refine multi-scale features before prediction. Experiments on a single-class soccer-ball dataset (2,474 images; 1,978/246/250 train/val/test) show that YOLO-P1P2-CBAM achieves 0.9398 mAP@0.5 and 0.6025 mAP@0.5:0.95, outperforming YOLO11n/s/m/l/x and two additional baselines trained under identical settings. Qualitative results indicate improved localization stability in cluttered scenes and at long ranges.
