So dominant have these two been during the clay-court season that anything short of a French Open title would be considered failure.
Yet both face challenges at Roland Garros.
Nadal has yet to play a five-setter since returning from a serious knee injury.
Williams must beat back the demons from last year's French Open, where she lost in the first round.
Still, the way Nadal and Williams steam-rolled over the competition puts the perennial powerhouses at the top of the list of who's hot heading into the French Open.
