My gut feeling is that he will miss out by 1 or 2 places (unless he beats Kyrgios of course). But with only 8 points to defend in the lead up to Wimbledon, it is only a matter of time. However, he has a lot of points to defend in July (75 in total) and if he is included in the DC squad but doesn't play, he will not have the opportunity to defend those points.
Strangely, I haven't seen his name on any of the challenger lists over the next couple of weeks so it will be interesting to see what his schedule will be on the grass.
There is almost no way that 511 points will be enough. There are 5 challenger events next week and most players ranked 100-120 will be playing in one of them. It would take an extraordinary string of results to prevent 2 or 3 players overtaking him.
I wasn't surprised that Kyle wasn't down for the first grass challenger week even before he qualified and reached R2 at the French Open. Now looks even better to take that week off.
And can't say I'm that fussed if he misses week 2. I assume that he will appear with a WC at Queen's in grass week 3.
Kyle will be top 100 soon enough so much less drama than with James ( or with what James is making it ). Ironically even before his R1 challenger result, it looked more sensible for James, even regarding top 100, to have at least taken this week off.
At first I thought I was odd that Kyle didn't enter Surbiton (I had never expected him to enter Manchester) but on reflection I think Queen's, Nottingham and Wimbledon is quite sufficient for him because as we have discussed before Kyle seems like the type who needs to manage his schedule well and have frequent rest periods. Had he failed to qualify at RG he might have had a change of heart and requested a wild card for one of the grass court challengers but having done well here I think that becomes unlikely.
While Kyle is unfortunately out with his stomach issue so retired hurt on 511 ranking points, he still clings on just to a top 100 spot.
Mahut's progress now makes his best case scenario WR 100.
While I agree with RJA that there is almost no way that will hold, and now more so with absolutely no wriggle room, it would be incredibly ironic if somehow it did, and with 511 ranking points being a total that James has been above.
