If you ask why Paula cant win much its due to her timing dependent motion.
The reason why is located here,
we can see her being stuck and she has no where to go, she now needs to lift her foot and stay on toe and arise her left shoulder.
For me, its amazing to see a tour level player with such bad mechanics. However it just means it just got a lot harder to win as her consistency wont be good. She is a outstanding putter which helps.
For me looking at Annika for example as she dominated and these girls cant do that and if they do they go see a swing guru like Yani tseng did and loose their game.
