Bring on the quarterfinals. And, potentially, bring on Andy Murray.
Djokovic used a solid serve (five aces, 82 percent of first-service points won) to establish momentum and set the tone of the match. He pounced on Robredo's second serve (winning eight of 14 second return points) as well, controlling play and setting himself up to advance.
He also won a solid 66 percent of his second-serve points and was aggressive from the start. Though he only saw two break points in this match, he won both and took advantage of his opportunities.
Robredo also only created one break point and failed to capitalize, as Carole Bouchard of L'Equipe notes:
Wait, Djokovic not broken while serving for the match ? ;) 6-3, 7-5 vs Robredo and awaits Murray or Tsonga in quarters.— Carole Bouchard (@carole_bouchard) March 25, 2014
It was a dominant and swift showing from the Djoker, who is carrying a nice wave of momentum as he moves on in the tournament.
After, Djokovic celebrated in his usual fashion, via tennis journalist Aca Stojanovic:

Thus far, Djokovic hasn't really broken a sweat at this tournament. He easily handled Jeremy Chardy in the first round, winning 6-4, 6-3, and Florian Mayer had to withdraw from their second-round matchup with a groin injury.
So he'll face either Murray or Tsonga feeling pretty fresh.
Obviously, the matchup everyone will want to see is Djokovic facing Murray. Djokovic holds an 11-8 record in the series, though the two have split the last 10 matches, with Murray most recently beating Djokovic in the final at Wimbledon last season.
Djokovic would likely prefer facing Tsonga, a player he's beaten seven straight times. Tsonga last beat Djokovic in 2011.
The Djoker certainly seems to have rounded back into form. Before this tournament, he talked to reporters about how important his title at Indian Wells was:
It was a relief for me. I haven't played many tournaments; I haven't played many matches. I knew I was playing well. I had an incredible end of 2013, so I did have confidence.
But I started doubting myself a little bit on the court. I was struggling a little bit with my, I would say, consistency and the concentration. Throughout the [Indian Wells] tournament, I had ups and downs, but I managed to win four out of six matches in three sets.
Mentally it's a very encouraging win that gives me confidence and that also is very special in a way. This time of the year I needed it very much, and hopefully I can carry that into this week.
A confident Djokovic is certainly frightening for the rest of the ATP Tour. It appears the Djokovic who has descended upon Miami is feeling pretty good these days.
Additionally, a rested Djokovic is even more dangerous. With a breezy run thus far through the tournament and looking to be in top form, anything less than a title in Miami will surely be a disappointment for Djokovic, regardless of whom he faces.
