This is the 17th season he has made at least 1 Masters 1000 final. Since he made his maiden final at these events (2007 Miami which he won) he has only missed out on 1 season (2010).
Sinner has to be favoured. Djoker could definitely win, either way it doesn't matter much in the grand scheme IMO. Sinner/Alcaraz still heavily favoured over him in b05 slams
