I can see that Jeremy is engaged in New Haven and Metz, just before and after the US Open.
I think he should play less ATP250 tournaments and concentrate more on bigger tournaments :
he plays many many ATP250 tournaments (New Haven will be his 11th one, World Team Cup excluded, Metz his 12th one
On the opposite, he played only 2 ATP500 tournaments. I think he should play the final two ones in the year : these indoor ATP500 should suit his game.
All the more as if he's top-30 in the end of the year (which is very possible
), he will have to count more ATP500 results mandatorily. And this year already, he has at least to reach the semifinal to be able to still get some ATP points in an ATP250 tournament : in an ATP500, a quarterfinal is enough.
Chardy doesn't look having a very solid physical : I think he should concentrate on bigger tournaments, now that his general level is really higher.
