Skupski was "one of the most decorated tennis players in LSU [Louisiana State University] history" as per the LSU webpage to which Steven links (the little u beside Skupski's name) on his Top 25 table. LSU is in Baton Rouge. So this is Skupski's "home tournament" in a way.
Yes, I'm sure the LSU connection has something to do with the WC. Maybe they gave Ken the choice of a singles WC or a doubles one and he took the latter?
