L.Rosol lost to B.Becker in the first round of US Open 2013 and B.Becker is going to meet N.Djokovic in the 2nd round.
And yes Nadal did lose to Rosol in the Wimbledon 2012 but for any H2H record a minimum of 3 matches must be played between them. I hope you got the point. :) And Davydenko is the only player a have better H2H record against Nadal.
