Feli Lopez. I know...not a remotely difficult match for Fed normally but the one from last night...
Possibly Feli Lopez...that's assuming he beats Kuznetzov and then doesn't lose his 2nd round match to either the winner of Pospisil\Verdasco. Lopez hasn't exactly been the model of consistency himself this year. Some experts were picking him for a deep run at Wimbledon based on his Queen's win...and then he promptly lost, sorry, retired, in the first round.
