Re: is sharapova's serve underrated?
the high number of DFs is also very easily explainable - she is essentially hitting two first serves all the time and not allowing other players to put her on the backfoot in her service games. She realized that she has little chance to win those 2nd serve points while just rolling the ball in, like so many other chicks do, so she probably decided - "screw it, I'm just gonna decide my service games one way or another on my own". Hence the DFs and all the 2nd serve aces and unreturnables
Those DFs are like a tap but the washer is broken and Maksim doesnt have a wrench.
Sharapova is so popular her owns fans have haters.
