Clearly you missed their match at Wimbledon, then?
Lol, let me rephrase that then. I think Kendrick was just a surprise for Nadal, that day, and the fact that grass is obviously Kendrick's best surface didn't help either. Nadal struggles a bit against big servers and big hitters on fast surfaces, it's no secret.
What I mean to say is that, I'd other wise expect Nadal to dispatch Kendrick in straights on every surface other than grass, maybe in 4 at Wimbledon because I think he'll have improved, but the fact that the roof is now closed could make the match slightly more interesting that it originally would have been.
