Biggest betting upsets in tennis?

[Tenez!]

I remember reading here about how Darcis-Nadal 2013 was the biggest betting upset in tennis history (41-1.01), and seeing a table of odds.

Does someone have the numbers?

41 is an unreal number for Darcis. Maybe some local bookie gave it but this doesn't represent the actual value of the outcome. I think that Soderling was around 24 in Bwin or Bet 365 vs Rafa.

In 2010 Falla was serving for the match against Roger and he was a huge underdog but can't remember the odds. Istomin was 23 against Nole in Australia.
