Rafael Nadal vs. Novak Djokovic at the final of Miami's Sony Open is the 40th chapter in tennis' most important ongoing rivalry. Only the matchup is redundant because the No. 1 ranking and championship stakes continue to be factors nearly every time these two fighters meet.
What's most interesting is the way this rivalry has evolved the past three years and how the twists and turns continue to produce new surprises and thrilling matches.
On one side, King Novak sets up as the ultimate ball-striking machine but with the savvy and moxie to attack his Spanish rival with the weapons of his choice. He looks to call the shots and should be confident in taking this match.
As always, El Toro Nadal will be hoping in his corner, eager to inflict his power and spin from anywhere on the court. He has the heart and belief to win big matches, but he must face down his most difficult competitor.
It's merely another title on the line but both will come out swinging once again. Who will win the all important final point on Sunday?
