so why did petzschner need a WC and bachinger not? does someone know the rulebook to confirm the fact that the alternate list is based on the ranking of the day when the draw is made? because in that ranking bachinger would be in front of petzsche..
I think the loophole is in this rule
If a withdrawal occurs after 12 noon, Eastern Time, USA, on Friday, the vacancy will be filled by
the highest ranked player from that event’s qualifying sign-in list and players from
the original alternate list who have contacted the on-site Supervisor prior to the
qualifying sign-in deadline and preserved their eligibility on the new alternate list.
A player can only preserve his eligibility on one list.
That is the only thing that actually makes sense, with Sela not getting in. Sela was also ranked higher than Petzschner and Bachinger but didn't get in.
Also based on the draw http://www.atpworldtour.com/posting/2013/6486/mds.pdf
as you can see Bachinger last acceptance with 109 and this is ranking history
so clearly the acceptance list was altered and was based on the most recent rankings
