Let's be honest, ask any player if they would prefer to win an asterisked Grand Slam or not a Grand Slam, and I bet all would say to win one however imperfect the circumstances may be. Assuming it goes ahead this year in August / September and that all who can play do play, who would be best placed to take advantage of the extraordinary situation? Given the lack of match practice in the runup, the lack of spectators, and the unusual atmosphere, my guess would be someone familiar with the courts but doesn't handle well the pressure of a crowd (be it for or against) and whose game does not need a lot of pre-tournament match practice to find their rhythm. Madison Keys could well fit in as her game does nto rely on rhythm or consistency, she has been keeping active in training, and the home crowd pressure could be gone. I wouldn't go for Serena (needs more practice beforehand and loves a crowd) or Andreescu (needs more practice). Perhaps Osaka as she doesn't seem to care about the crowd but she seems to have other things on her mind lately. On the men's side, I can safely say that it would be Djoker again.
