Naomi Osaka rolled past Danielle Collins 6-4, 6-2 in the third round of the BNP Paribas Open on Monday night, keeping the world's No. 1 player on track to defend her title.
World number one Naomi Osaka was trying to find the positives after her Indian Wells WTA title defense went up in smoke on Tuesday.
Osaka, who parted ways with coach Sascha Bajin after winning the Australian Open and becoming the world No. 1 in January, is also confident that her decision to bring American coach Jermaine Jenkins into her team is working out.
"It gives me confidence that I can turn around matches, that I can play also three sets, also in the close moments that I'm there, that I can trust myself", said Kerber, adding that it was always hard to face an opponent for the first time. "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 think, given the circumstances, I tried my best and I don't really have any regrets".
She won the WTA title in Toronto in 2015 before a series of back and wrist injuries saw her slide down the rankings.
The victory over Osaka came in "very high" in her list of big wins. "It's extra motivation for me to play just a little bit better out there".
She next faces Estonian Anett Kontaveit, who was leading 5-0 against 11th-seeded Anastasija Sevastova when the Latvian retired from their match. I congratulate him for playing tactically really well and getting me out of my comfort zone. "I think that we are all sort of on the same page, and we are all looking forward to Miami", she said.
Halep, who received treatment for blisters on her foot during the match, hit just six winners and piled up 36 unforced errors. I was running too much and too defensive.More news: Tommy Fleetwood makes fine start to the Players Championship

She added that despite failing in the first title defence of her career, she thought she had handled the challenges well, saying: "I didn't lose in the first round".
Osaka was also in Dubai, but lost her first match in the second round to Kristina Mladenovic, resulting in an emotional press conference where she admitted to struggling with her new position as the leading player of women's tennis.
Angelique Kerber, meanwhile, survived to earn a quarter-final showdown with Venus Williams.
In their first head-to-head in last month's Dubai Championships, the Japanese star was sent packing by the 67th-ranked Hurkacz after a shock second-round defeat, also in three sets.
Earlier in the day, Czech teenager Marketa Vondrousova ran Halep ragged before dumping the Romanian out of the tournament 6-2 3-6 6-2.
Hurkacz, unseeded, reached the fourth round of a Masters 1000 event for the first time in his career.
Andreescu improved her match record for 2019 to 25-3, including qualifying, as she became the youngest player to make the last eight at Indian Wells since a 17-year-old Anastasia Pavlyuchenkova reached the semis in 2009.
Fifth-seeded Karolina Pliskova eased past qualifier Ysaline Bonaventure 6-3, 6-2.
