Lots of players, especially in the bottom half, who are either out-of-form or don’t like these conditions…
Shang is the defending champion and I’d like to see him do well, but it seems unlikely given his lack of matches this year. I could see lots of the seeds struggling. Griekspoor has barely won a match since the grass season. Sonego has been poor all year outside of the AO and Wimbledon. Baez has only won 2 matches on hard courts all season and Darderi's record isn't much better.
I’m thinking that Nakashima might make it out of the bottom half. No real idea about the top half -Musetti made the final here last year, but there's a few dangerous players in his half. Atmane could be a loose cannon, Botic's unpredictable, and Wong's definitely one to watch as well. And then I have a question mark over GMP, who hasn’t looked nearly as good this year as last, but I wonder whether he might start picking up some better results in this part of the season - he's in trouble if he doesn't.
