Who are the biggest spoilers in tennis history in Open Era ? Who else came very close to being a spoiler and could have changed the landscape ? If Nadal is not able to come back or if Nadal is not the same player he was till recently, Rosol would rank as the biggest spoiler in tennis history in the recent past. Basically someone who ended the career or changed the "tennis scene" in a huge way. Tsonga comes to my mind as a person who missed out on being a "huge spoiler". Tsonga beat Nadal at AO 2008 Semis, won the first set in the finals against Nole and was close to making it 2 sets all in the finals. If he had won, probably Nole may never have won 5 slams or be the player he is now.
