Top 50 looks a million miles away frankly. He's a way back in the race, probably about 200 or something similar, so a lot of work needs to be done in this second half of the season to at least retain something close to a top 100 spot. Personally, I'm doubtful whether he can do it. He needs to win big in the post-Wimbledon clay ATP events in Germany where he will no doubt feature with or without a wildcard, and challengers will be key too.
Why foolish? Of course he is better on clay, but this is a weak challenger, where he could gain a lot of points with a semifinal?
I understand his thought process. He wants practice on hard-courts before (presumably) he goes to the States for the weeks leading up to the US Open.
The reason I think it's foolish, is he's going to be reacclimatising several times this summer. It's not ideal for building up form, which he badly needs. It's more than likely he'll be in the doldrums outside the top 100 next year.
The points are really going to start being shaved off now. Three challenger wins, a semi-final & some other minor performances will drop off in the next two and a half months. Now is as good a time as any to get it together, Cedrik.
