All fair points. I still consider Sinner to have about a 75% chance to win.
Agree completely with grass being Sinner's worst surface. I think he prefers a high bounce, so even though clay negates his power a little bit, the ball sits up right in his strike zone nearly every shot. Hard courts give him the best of both worlds, high bounces and decently fast conditions.
The injury thing will be interesting. I've gotta think at least one of them has an injury show up and impact their play. Either Sinner's elbow, or Djokovic's groin? hamstring? I couldn't tell what he tweaked in the final game yesterday.
