According to Tennis Abstract , Billy and Stuart are the two highest ranked players in world that have never played a Challenger event. Felix features in the top 10. Ali also features in the top 10 of players that have never won a challenger match.
Presumably all 4 of them will get chances in the grass season to fix those records .
I assume this is Challenger main draw. Pretty sure Billy has played qualifying in the past.
