Copying part of my post in the Menorca Challenger thread ( where he has lost in R1 ), showing that in retrospect Billy was essentially just one win ( in a winnable match ) from being top 100 in the post Miami 31/03 rankings.
"As the Miami fortnight and challengers shook out he was in retrospect very close to being top 100 in the current rankings. He is WR 103 on 580 points, WR 100 is on 592 points. If Billy had won his 3 set MD R1 match vs Spizziri he would have had 20 more points taking him to 600 points. So, all else being equal ...
He is now live ranked 104 and if he moves further this week, it can now clearly only be one way. He still though has a window before the grass season. But he needs to push that possibly tighening window open."
