I thought the ATP had a standardized test for prospective umpires, administered in German?Pretty cool little game by the WSJ. There are always threads about line calls. So let's see how good everyone is.
I was wondering the same thing. Are they instructed to follow the ball or are they just staring at the line waiting for the ball to strike.15/20. That was tough. Do line judges concentrate on the line or do they have an idea of where the ball will be hitting by watching the player on the other side hit?
