Roger Federer continues hot form, downs Federico Delbonis at Indian Wells

Japan's world No. 109 Taro Daniel pulled off a major upset Sunday at the BNP Paribas Open by beating Serbia's Novak Djokovic in the second round.

It was a determined Delbonis who looked to have been eased by the clearer conditions and he forced Federer to rescue a break point in the second game after the restart.

Djokovic, who returned to the tournament following his elbow operation was yet to come to his best shape. The 10th seed was appearing in his second tournament of the year (Round of 16 at the Australian Open) after undergoing a "small medical intervention" on his right elbow last month.

The 10th-seeded Djokovic acknowledged his poor performance against the world's 109th-ranked player.

Both Canadians in action lost, as Denis Shapovalov fell 7-6 (3), 6-3 to 30th-seeded Pablo Cuevas of Uruguay, and 20th-seeded Adrian Mannarino of France defeated qualifier Peter Polansky 6-1, 6-4. Striking his groundstrokes with conviction and refusing to concede the momentum shift, the Japanese would benefit from 22 unforced errors by Djokovic to snatch the opener in a tie-break.

Federer's second-round match-up with Delbonis was delayed in the second set on Saturday due to rain, and the Swiss was intrigued by the opportunity to take on the same opponent for the second day running as he triumphed 6-3 7-6 (8-6).

The world No.1 - who has a flawless 13-0 record this year - is the defending champion and is bidding for a sixth Indian Wells title.

The 34-old, who has seven career titles, pounded down 12 aces, including six in the deciding set. I was - I felt close, but, you know, didn't been able to come back.

Federer will face 25th-seed Filip Krajinovic in the third round.

"I mean, I just completely lost rhythm, everything", he said.

"To me, it's not that surprising", the defending champion said in California.

However, Daniel bounced back as he won the third set comfortably to clinch the match.

The Serb failed to serve out the first set, growing the internal seed of doubt and emboldening Daniel, who at last year's US Open took a set from eventual champion Rafael Daniel.

World number three Marin Cilic also won Sunday, defeating Hungary's Marton Fucsovics in straight sets, 7-5, 6-3.
