Tennis is a bit of a mess right now.
A player like Ruud is now #2 and would even have been number one if he had beaten Alcaraz.
In the past a Del Porto or Wawrinka had to at least win 2 matches against the big 3 (or 4 including Murray).
But now it’s much different. Big names are gone, old, or unvaccinated… and new gen is injured or too unstable: Zverev, Tsitsipas, Kyrgios, thiem (not new but gotta name him). Sinner was good, but also not there yet.
Alcaraz the only new talent who really delivers at this moment
