Hello, can you help me with umpire gestures used on clay? There are two: first one is that umpire points his finger up and second is harder to explain-his hand is lower and all his fingers are straight. So logically I always thought when he do the finger-up gesture it means overrule and when he do the second gesture it means that ball stands. But according to what always commenatators say I found out that it is probably quite the opposite. Can you explain me how it works? Thanks.
