If you haven't been following, Justin Rose addressed a chip the other day behind 18 green. He was about to draw the club back when he quickly stepped away. He brought Sergio over and indicated that the ball may have moved. They both watched one of the screens surrounding the green which had the replay, and to their eyes, it did not move. Rose played out and made 4. In the scoring tent, the rules officials concluded that video evidence showed that the ball did move and he was assessed two strokes for playing the ball from the wrong place. However, they later discussed that it required the use of sophisticated video technology (the so called HD rule) to see the move, and rescinded the penalty. Rose is now at -10 and two shots off the lead...
My questions would be:
Why would Rose quickly back off unless he perceived movement?
Why couldn't they apply the "HD rule" right off the bat?
