Jim Courier had some thoughts on Rune's game, while calling his SF match,
" It's still a very immature game- he needs a sense of order"
Personally speaking Rune and his shot selection at times, is poor, especially at this level, he has the shots, though sometimes he dosent think and rushes, he tends to lose focus, needs to be more patient in the rallies.
BTW Zverev with his win in the SF now has passed Alcaraz into No 2.and will be seeded No 2 at the ATP Finals, making a Sinner v Alcaraz clash already in the group stage.
