Charles is another Brit pushing for French Open qualifying entry.
He is live ranked 260 on 206 points ( after Felix, now live ranked 252 on 216 points ) and that is 2 more points banked ( 4 if he qualifies ). And like Felix he has no ranking points to drop before the French Open Q entry list comes out.
Assuming that a ranking of 220 will be sufficient to secure direct entry for French Open qualies - this means that Charlie needs to find approx 56 points by the time of the cutoff (late April/early May?)
Probably a long shot although he is seeded 2 - title here would see Jan into the top 100
Certainly live rankings show the resulting 618 points would have him at #95. That though is before everyone else gets round to adding whatever 2 weeks of ranking points so it might not stick. Would be very interesting even if just getting close for now.
