Novak Djokovic stunned by Philipp Kohlschreiber at Indian Wells

Defeat was hard to take for Djokovic - who returned to win in the doubles later on Tuesday - but he was not dwelling on it, particularly with another big tournament on the horizon. "I had to get over it in an hour, because I played doubles", said Djokovic, cracking a smile.

It is the second loss of the Japanese world number one after she lifted the Australian Open trophy and the 11th consecutive win for 22-year-old Bencic, who came to Indian Wells with a Dubai Tennis Championships title.

Kohlschreiber posted his first victory over a top-ranked player, advancing to a fourth-round match against France's Gael Monfils.

The Serbian had a 1-0 lead when the match was halted by rain Monday night.

No. 2 seed and three-time Indian Wells champion Rafael breezed by Diego Schwartzman 6-3, 6-1.

He committed 27 unforced errors, converted just one of his five break point opportunities and destroyed his racket at one point when frustration boiled over on a sunny day in the Southern California desert.

Williams will fight for a semi-final berth against eighth-seeded Angelique Kerber, who beat ninth-seeded Aryna Sabalenka of Belarus 6-1, 4-6, 6-4.

Spain's Muguruza, a two-time Grand Slam champion now ranked 20th in the world, out-lasted seventh-ranked Kiki Bertens 5-7, 6-1, 6-4 while Williams, a seven-time Grand Slam victor, beat Germany's Mona Barthel 6-4, 6-4.

In another upset earlier, Pole Hubert Hurkacz fired 10 aces en route to a 4-6 6-4 6-3 win over world number seven Kei Nishikori of Japan to reach the fourth round. Her triumph in Australia made her No. 1 for the first time, but her time at the top has been rocky.

"I tried my best and I don't really have any regrets", said Osaka to media.

"Overall it's not been easy playing Stan", Federer said.

"It's a very special win today", Kohlschreiber said after the match. "Honestly, at a time like this with that scoreline, I would usually feel very depressed and sad".

The display of emotion didn't change anything as Kohlschreiber opened the second set with a service break and broke Djokovic again in the seventh game to give himself a chance to serve for the match.

Nonetheless, Djokovic's Indian Wells campaign is not yet completely over as he is still alive in the doubles, where he, along with his partner Fabio Fognini beat the pair of Jean-Julien Rojer and Horia Tecau in the quarter-finals.

Bianca Andreescu, an 18-year-old Canadian, beat 18th-seeded Wang Qiang 7-5, 6-2.
