I follow the livescores of the qualis and Golubev bt Cermak 6-2, 6-3
OK, so he might have replaced (WC) Nedelko as alternate.
Frantisek would have a decent ranking in singles if playing more these events. When he was suspended by ATP for few weeks, because of gambling, he played a futures (ITF event) and won the title
just checked his career high in singles was 201(Oct 2003), but he always do quite well when plays ATP events, by qualifying and playing close matches with the "singles specialists"
