There are 7 minutes to go in the final day of a Test. The batting team requires 3 runs to win and are 232/9.
The bowling team seems ready to go, but then they decide to adjust the field. The captain still is not happy with his field, and he adjusts again. By the time the field is ready, there are only 3 minutes left. No extensions, as you have already taken the extension.
As the bowler runs in, the tail end batsman steps out of his stance, claiming something behind the bowler's arm. You look back. There is nothing that you can see.
What do you do?
