Rafael Nadal is in cruise control against Andy Roddick in a very one-sided US Open quarter-final so far.
Nadal will be wary after Roddick's superb four set win over fifth seed David Ferrer, a match which many people did not expect him to win. However Roddick has always saved his best for the US Open. No one appreciates the atmosphere of Flushing Meadows more than the 2003 champion, whether he's competing on Arthur Ashe stadium or slumming it on court 13.
Roddick's head-to-head record with Nadal is not good (whose is ?) but he's always given the Spaniard his fair share of problems. Nadal may have won six of their nine matches but he knows he's in for a tough time against Roddick, just scraping through their ATP World Finals match last year 3-6, 7-6, 6-4.
Roddick must play exactly the same sort of tennis which brought him so close in London, come out serving consistently huge, attack short balls, get to the net and try to ensure his approach shots aren't too predictable.
However Nadal has been quietly improving through the rounds. He's yet to face anyone of Roddick's calibre but he's been steadily moving his game up a few notches. He knows what it will take against Roddick and he'll be focusing on imposing his kicking forehand on the match to yank the American round the court unless his lungs can take no more.
Roddick is never given enough credit for being such a gritty competitor and he'll stick with Nadal but ultimately it's unlikely to be enough.
