Mayer would instead play lucky loser Ruben Bemelmans-who he defeated, 6-4, 6-1, in just over an hour.
"But, you know, after an opponent like this, to come back from two breaks down, actually, for me it was nearly impossible". After another 90-minute delay organizers suspended play for the night.
The 12-time major victor led 5-2 in the opener, but Daniel fought back well to clinch the first set on a tie-break, and although Djokovic pulled level, 61 unforced errors from the five-time champion saw Daniel clinch victory after two-and-a-half hours.
Federer needs to make the semi-finals to retain his number one ranking. Federer said on Thursday that he won't be taking anyone for granted in this draw. Canas defended his second serve better and he outplayed Roger from the baseline to score one of the most shocking results of the season, saving two out of three break points he faced and stealing Federer's serve four times from seven opportunities.
By virtue of the win, Federer moved on to the third round where he will face No. 25 Filip Krajinovic for a spot in the round of 16.
Novak Djokovic produced a puzzling performance as the former world number one lost to Japanese qualifier Taro Daniel in the second round at the BNP Paribas Open in California on Sunday.
"But obviously having played only a couple matches in nine months, you are still in a way battling inside of your mind whether you are fit or not", Djokovic said. "Very weird", Djokovic said. He lost to Chung Hyeon in the Australian Open fourth round in January before undergoing the surgery.
But the decision backfired as he peppered the court with 61 unforced errors and totally faded away in the third set in the second round clash that lasted 2 hours 30 minutes. "Just didn't feel good at all, nerves were there". Djokovic even admitted that he lacked rhythm in the game.
"To me, it's not that surprising", he said. "And even though you don't have pain, you are still thinking about it because it's something I've been feeling and dragging for over two years". "And I just have to work really hard and keep that motivation high to be able to win matches". Because if I change and I start to put, like, kind of like first, second serves in to try to play with first serve, but then also doesn't hurting him so much, maybe, you know, he was returning so much, like, on top of the line, if he connect two or three good returns, it was going to be tough.
Daniel, who is ranked 109th in the world, advanced to the third round where he will face Gael Monfils of France who outlasted American John Isner 6-7, 7-6, 7-5.
Marin Cilic, the 2014 U.S. Open champion who lost to Federer in the final of this year's Australian Open, eased to a 7-5, 6-3 victory over Marton Fucsovics.
