The situation, of course, brings back the bad memories of the 2017 ANA where Thompson incurred a four-shot penalty during the final round for not replacing her ball correctly on a putting green during the third round. Thompson lost the lead and eventually the tournament. The first two strokes were for not replacing the ball, and the other two strokes were for signing an incorrect scorecard. Thanks to a USGA rules change that allows the implementation of a local rule, those second two strokes would now not be applied.
