Yes but Roger was probably fairly consistent throughout. Bottom line is he had a big physical decline by the time he was 29. He can still play decent tennis sometimes but clearly way past his best
And that feels like a good time to say what we all know that one of Thiem's problems, everywhere, not just here. But mostly against these top players is he does not return as well as Novak or Rafa. Or even Roger.
And that point shows why Nadal wins so much. He is more willing than anyone to move his body to create a shot that will finish or set up the final shot of a point. Nearly slid into the net there.
