How many GSs do you predict the talented Gauff will win? She's already reached the 2nd week of a slam at just age 15, her game is building and coming together nicely, she is proving she has the mentality to win infront of packed out stadiums with pressure on her. It is only a matter of time before she pulls a Hingis or Sharapova and wins a big one at a young age. And from then on, it just depends on how hard she works and how willing she is to stay consistent and be the best. So how many slams do you think she'll win by the time she retires (which is hopefully, for the WTAs sake, when she's at least in her mid-30s).
