As the title said. Who has been their country #1 for the longest time? Someone from a small country who played for a long time, surely, but who?
Federer became Swiss #1 15/1-2001 and will thus achieve 13 years in January, but I do not think this is a record. Can't think of anyone better off my head, though. Lendl blew his chance by switching nationalities. Any ideas?
Sargsian: 13/7-92 to 14/8-94 and 10/7-95 to 14/8-06. In total just over 13 years. Quite a bit behind Delgado, he'll be passed by Federer soon.
Nieminen: 30/7-01 to date. He'll have to keep at it for some years more to be a contender.
Filippini: Not a candidate. Back-and-forth in 1988, overtaken 00. Maximum just over 12 years.
It may be a player from a really small country whom we have never heard of and only plays a few futures/challengers per season. Players that we know typically have achieved a high ranking, and such players typically retire before age 35. Very low ranked players may continue to play small tournaments up to much higher age.
Supporting Federer, Murray, Karlovic, Almagro, Gulbis, and Tomic.
