It might just be more of the standard Kyrgios getting up for the big time matches. He fell far enough down the rankings to have to play three both extremely high quality and big name opponents in a row and we know how much he loves those matches. And up next yet another big scalp, Zverev. Can't remember the last time someone had to go through four former or current top 10 players to win a grand slam title, let alone a 500. Maybe Fed in AO17?
