You rarely beat someone 0-0-0. But the match would not be competitive as a whole. Rarely would you see them in control of a pt.
Match play stems on the serve and the return, rafa would control the first ball every point, you think haelp has a big serve? It may bounce twice by the time it reaches nadal
Women hit a different ball (literally) than men, theirs is much lighter and usually in the strike zone. Rarely do you a wta player returning shots over their shoulders, so they will be a bad position on most.
Have you ever played someone who hits massive top like rafa? Everything is up there and makes it very hard to come through it. Like returning a good kick serve.
