In their Wimbledon match, Cibulkova hit 56 winners at Radwanska.
In reality, I believe that Cibulkova's true number of winners in that match must have been at least over 100 if not 150.
Winners are easy to count. What is harder to count is the number of anti or reverse winners Radwanska was also hitting; how many absolute winners did Cibulkova hit, full power, into the corners, at the lines, which Radwanska was able to run down? Not just that, but to recover, AND bring the ball back also JUST within an inch of the lines and the corner so as to completely reverse Cib's winning shot, not just to retrieve it, while you are still on the defensive and the other person still has control of the point, but to completely reset the ball to neutral, so that Cibulkova had to setup another attacking move to find the winner again. This is what I call anti/reverse winners, which although is more subtle skill, is to me is no less impressive than going for the winner. At least, therefore, Radwanska hit 50 or 100 reverse winners.
