People have to keep in sight that Nadal lost only match between 2005 and 2014 in RG, and in that year he had already won the Australian Open, Indian Wells, Monte Carlo, Barcelona and Rome. Plus, he was winning very easily his matches before facing Soderling, including a crushing victory against Hewiit the round before...So, yes. It's pretty much unthinkable not to rank this as the biggest upset ever in tennis, and maybe even in sports.
