Karlovic is the third-highest of all time for most aces in a match, at 78. He could surpass that record today. The record still stands with John Isner though, who leads with 113. Right behind him is his rival in the pair's epic match - Nicolas Mahut, who has 103.
Right now, the points are coming Verdasco's way more or less because of errors by Djokovic. It's feeling more and more like the Spaniard is just biding his time, waiting to finish. Djokovic is now just one game away from progressing to Round 2.
Meanwhile, Djokovic has a 4-1 lead in the third - and what looks to be the final - set. Verdasco has been a fiery, if mercurial presence here, and although he looked incredibly threatening on multiple occasions, he just was not able to build on it. Crucial errors - and perhaps his own temper - have let him down here.
Verdasco has held serve once in this match; and at 3-1, Djokovic is looking a bit tired but wanting to finish this off. Verdasco is visibly irritated here, and unfortunately that frustration translates into him netting what would've been an otherwise good return.
Third set now underway, and Djokovic straightaway takes the break to lead 2-0. One can't help but feel for Fernando Verdasco, who is visibly frustrated after an excellent attack does not go his way. He looks as though he has given up a little bit.
And it's now dead even at 4 games all. Not as one-sided as the first set, certainly, with some good stuff from Fernando Verdasco. But although he's applying the pressure on Djokovic, he's unable to hold on to leads and breaks here.
The players are now an even keel, as Verdasco leads 4-3 with Djokovic on serve. The Spaniard looked threatening early on, but right now he's missing out quite a bit. That said, Verdasco's putting quite a bit of pressure on and Djokovic is committing a number of unforced errors.
