Instead of ripping through Federer, a sloppy Djokovic was broken to start the second after a slip on the grass. With Djokovic serving at 4-5, 30-all, Federer produced a stunning drop volley to earn a set point, only for it to be erased thanks to a fine Djokovic serve. It was soon 5-2 and that second break was pivotal, since Djokovic got one back at 2-5 despite Federer winning an epic 35-shot rally. A Federer into the net on break point led to groans.
