<p>SECOND SET: DJOKOVIC 2-6 6-3 NADAL*In this age of topspin, the return is the most important shot in tennis - and two of the best in the business are showing just why. Novak skews a tight forehand wide and it's 15-30, but he's battles on, reaching set point when Rafa fails to steer a huge smash just long. What a set this has been, 58 minutes of ebb and flow, gruelling exchanges and the odd stroke of genius or six. Novak takes the second set.</p><p>SECOND SET: DJOKOVIC* 2-6 5-3 NADALJust as quickly as he seemed to have found his feet in this final, Djokovic can suddenly look lost again. Expressionless, half a beat too slow, he's 40-15 down before another flash of what he's capable of, with a forehand winner that flashes across Nadal into the ad court. In spite of his travails out there, as much with himself as with Nadal, he's finding a way in this set. Screaming to the heavens. Lashing out. Playing it safe. Whatever it takes.</p><p>The game is through seven minutes, and Nadal suddenly finds himself on the receiving end of some bold plays from the Serb. These servicve games aren't getting easier, that's for sure - and once more Djokovic reaches break point by pinning Nadal back with that prodigal down-the-line backhand, and we're into another cat-and-mouse epic, only it's Djokovic attack Nadal's backhand. Rafa opts for a drop shot but it's the wrong play, and Djokovic snaffles it with a flourish. He's broken again, and will serve for the set.</p><p>SECOND SET: DJOKOVIC 2-6 4-3 NADAL*Oooh, that first serve was in, Novak - you should have called the line judge up on that one. He hasn't, and he double-faults, and he's missed one, and with a punchy 'vamos' Nadal awaits the first of three break points at 0-40. Djokovic is playing his best to stay in touch right now, cutting off an exocet of a forehand from Nadal on the run with another stop-volley and saving the second as Nadal nets, but it's that forehand again, driven inside-out with too much venom for the Serb. Rafa breaks, the crowd goes wild once more, and we're back on serve.</p><p><a href="http://www.telegraph.co.uk/sport/tennis/usopen/10296757/US-Open-mens-final-2013-Rafael-Nadal-v-Novak-Djokovic-live.html">Keep reading...</a></p>
