DOHA, Qatar (AFP) — Naomi Osaka put last week's first-round defeat in Abu Dhabi behind her with a straight sets defeat of 15th seed Caroline Garcia at the Qatar Open on Monday.

This was former world No. 1 Osaka's second win from the five matches she has played since returning last month after a 15-month time out on maternity leave from the tour.

The Japanese four-time Grand Slam winner was exacting a small measure of revenge on Garcia with this 7-5, 6-4 success in Doha as it was the French star Garcia who knocked her out in the first round of last month's Australian Open.

And she reckons that she is beginning to find her stride again after becoming a mother.

"I feel like I'm a much better player now. In Australia, my returns weren't as good and I don't feel like I was as focused as I am now," the match winner said.

On coming back physically after pregnancy she added: "It's been a really tough journey."

"I felt like I was chasing myself in the past and it honestly wasn't really healthy to do."

"After giving birth, I feel I trained really quickly, I'm a very big perfectionist and it's tough when you don't see results as quickly."

"I felt like I was driving a car that wasn't mine so my body didn't feel like the body that I was used to."

'I feel like I'm a much better player now.'

"It was in that journey I felt like I learned how to love myself as I am now. I got to wake up every day and see my daughter and know that I was strong enough for her to come into this world."

Osaka's next assignment on her comeback trail is a second-round date with Petra Martic of Croatia.

This is the second time the pair has crossed swords but it comes a decade after their first encounter.

A 16-year-old Osaka prevailed on that occasion, a final qualifying round match at Stanford in 2014.
