Hunt ignored several of Kovacs' serves, allowing them to harmlessly fly by. In short order, Kovacs also sat on his baseline and Forest Hills experienced what was called "tennis' first sit-down strike." About five minutes went by with the crowd alternately cheering and jeering. When order was restored, Hunt went on to win the match in straight sets.
