How Dominant is Rafael Nadal?

From Straight Sets:

Novak Djokovic and Rafael Nadal play in the finals of Roland Garros on Sunday in a match guaranteed to make history. A Djokovic win would be his fourth straight major title. While technically not a Grand Slam (which must occur in the same calendar year), it would nonetheless be an astonishing accomplishment. For Nadal, a victory on Sunday would give him a record seventh French Open title, eclipsing Bjorn Borg, and further cementing his reputation as the best clay-court player ever.

In this chart, each square represents a game won; each row is a set. What I hope this shows, is how little traction Nadal's opponents have found.

Nadal enters the final without having dropped a set. Only one opponent has gotten to a tie-breaker. Djokovic, meanwhile, went to five sets twice and nearly lost in the quarterfinals to Jo-Wilfred Tsonga.

My money's on Nadal making history here. But Djokovic should never be underestimated.
