Respectfully, wouldn't it be the opposite?If the courts are playing fast, a player with a relatively weak serve like Sinner will be more disadvantaged especially for day matches. He is probably hoping that he will get scheduled for some humid night matches under slower conditions when he plays higher seeds.
We will see - he is playing against top pros, their better serves might be hard to break on fast courts and he might lose a bunch of tiebreakers or one-break sets to lose a match against a good server. I feel that a lot more guys in the top 50 get dangerous on fast courts if they have a big serve and FH. On slow courts including clay where there are more breaks of serve of all players, superior baseliners like Sinner who hit with a lot of topspin seem to do better.Respectfully, wouldn't it be the opposite?
In other words, fast courts and hot conditions would enhance the effect of an otherwise average serve, right?
For me personally, I don't have a huge serve. I top out at around 110 mph if I'm really going for it, but usually rely more on spin and placement, making my average serve more in the 85 to 90 mph range. On a slow court or in humid conditions, my serve can sit up and give returners just a fraction more time to smack it. But if I am playing on grass or a slick hard court, especially at altitude or in hot dry conditions, the effect is that my serve skids through and I get more free points, making it easier to hold.
Given this, I would think a fast court helps Sinner hold serve more, while his return game (which is pretty good) might be a little more challenged, but is still a strength given his fast hands and timing.
