You're probably one of few people to score points on this question. From what I've seen, most people have tipped Sabalenka against ?wi?tek.
But congratulations to Pegula, very strong performance and also very surprising, would definitely have been a good betting odds, but unfortunately not bet on this game, and also not at BSFL.
You're right, many thought that Sabalenka would win against ?wi?tek, but she proved otherwise. Too bad you didn't bet on this match, you would have made a great profit! Good luck with your next bets!
