And well done Billy - the players here are in quite a tight ranking group so seedings probably dont mean too much here (not that they appear to anywhere right now eg New York where 6 of 16 men disappeared opening day!)
For Charlie, it is his first ever Challenger win, so well done to him !
Ali has pulled out of next week so must have an issue most likely injury. Also means his top 250 status will only last one week after the US Open sadly.
Would expect he would pull out of Istanbul the following week. It does however mean Charlie is direct entry next week.
