Rafael Nadal's progress at the Indian Wells Masters continued on Wednesday while world number one, Novak Djokovic as well as women's defending champion, Naomi Osaka have been eliminated.
Nadal advanced to the fourth round with a straightforward 6-3 6-4 victory over Filip Krajinovic, but Djokovic failed to progress as he was knocked in the third round by Philipp Kohlschreiber.
The Spaniard had dropped only six games in swatting aside Jared Donaldson and Diego Schwartzman in previous rounds and although his unseeded opponent more than doubled that tally, there was little danger of the three-time champion failing to reach the quarter-finals.
World number 113 Krajinovic was aiming to become the first qualifier in 16 years to make the last eight at this tournament, but he was simply outclassed by the 17-time major winner.
Nadal, last victorious at Indian Wells in 2013, was able to cruise into this year's quarters, where he will meet the winner of John Isner's match against Karen Khachanov.
Novak Djokovic lost his cool after being beaten by Kohlschreiber
Djokovic broke his racquet in anger after Kohlschreiber - who had lost his past seven matches against the 31-year-old - took the first set.
The match between Djokovic and Kohlschreiber began on Monday but was delayed until Tuesday because of heavy rain.
In the women's event, world number one Naomi Osaka's defence of her Indian Wells title was ended in round four by Belinda Bencic.
Naomi Osaka denied the chance to defend her title at Indian Wells
Japan's Osaka, who holds the US Open and Australian Open titles, was beaten 6-3 6-1 by the Swiss world number 23 in just over an hour.
World number two Simona Halep of Romania is also out, beaten 6-2 3-6 6-2 by Czech teenager Marketa Vondrousova.
It was a first win over a top-five player for the 19 year old, who is ranked 61st in the world.
Halep's defeat in California means 21-year-old Osaka, who claimed her first WTA title with victory at Indian Wells last year, will keep her number one ranking, despite losing to 22-year-old Bencic.
"I didn't play that well," Osaka said. "Honestly, at a time like this with that scoreline, I would usually feel very depressed and sad.
"But I feel pretty good right now because I tried my best and I don't really have any regrets.
"She was just playing so well. There wasn't anything that I could do in that situation."
