1. This is a grid labeling exercise based on the provided visual description of a soccer field marked with rows A to H and columns 1 to 12. 2. We are asked to identify the coordinate cell where a soccer ball is hidden on this grid. 3. According to the description, the ball is located "around (G,10)", which corresponds to column 10 and row G. 4. This coordinate is near the top right side of the goalpost in the image. 5. Thus, the ball’s position on the grid is cell $\text{(G,10)}$. Final answer: $\boxed{(G,10)}$
