Look, these young women are extremely talented. They work as hard as the men who are training for college and the pro circuit. NTRP men does not equal NTRP women. Physical limitations in strength and speed affect the outcomes of tennis. That is why we have leagues and women compete separately from men. Just as how children compete separately from adults and seniors are in different divisions than young adults. Even colleges separate themselves into different divisions. This is the same reason why my parents never expected me to play basketball- if you are a average man in size and weight, you just can't compete with college or pro NBA players, regardless of talent. There are two men in the NBA who are 5'9 or shorter- that means maybe 1 in a billion. So a 110-120 pound woman trying to outhit or outserve a 180 lb man is just a huge mountain to climb. Serena has the muscle strength to outhit many men, but then with her weight, is her movement comparable? She was shown up by a no-name challenger man when she boasted about how she could compete on the men's tour.
