In his first tournament since his return to number one in the ATP Rankings, the defending champion faced 25th seed Krajinovic for the first time.
It took less than an hour for Federer to see off the world No. 28 on Stadium 1, with Jeremy Chardy standing in the way of a place in the quarterfinals. Djokovic even admitted that he lacked rhythm in the game.
"Very weird. I mean, I just completely lost rhythm, everything".
"I was grateful to be out on the court after surgery that quickly". But at the same time, just didn't feel good at all.
"You're still battling inside of your mind", he added, referencing his recent elbow surgery. As in Federer's previous match, it is unlikely to be a complete walkover, but it is also unlikely that Federer will be pushed too hard.
"So talking about faster, I just think there is more bounce to it, especially if you play someone who has a lot of spin like he has and kicks the ball around a lot".
"I was not even supposed to be here because of the surgery that was only five, six weeks ago", said Djokovic.
"But he's strong enough to deal with that, and I love him and I want to see him in the top positions very soon".
Verdasco's first serve proved nearly unplayable in the deciding set of the second round match as he improved his career head-to-head record against Dimitrov to 2-2. Playing aggressively and making Djokovic move, Daniel would quickly erase the deficit and would end up taking the first set in a tiebreaker.
Speaking after his upset win, Daniel said the Djokovic he bounded out of the tournament was not the one the tennis world is used to admiring.
Novak Djokovic produced a puzzling performance in his loss to Japanese qualifier Taro Daniel.
As for Djokovic, the question now is whether he will play in Miami later this month.
Argentina's Juan Martin Del Potro (6) defeated Australia's Alex De Minaur 6-2, 6-1 to set up a third-round match with Spain's David Ferrer (29), who beat American Tim Smyczek 6-2, 7-6 (3). "He's only going to get better from here". It was actually quite interesting.
