There are 4 guys you just don't want to meet in R1 at RG: Nadal, Federer, Djokovic and Berdych.
The usual R1 destruction from the Czech, he always start strong when he's in a good form.
You probably missed last year's tournament here in Paris. Berdych is definitely not among the top 4 players to avoid in R1, he's actually unexpectedly prone to R1 scares (and even defeats - he's lost R1 in 2 of the past 7 Slams) for a player of his talent and ranking. Even in his best ever Slam performances, he had some early round scares.
