Serena Williams recovered from a first-set loss to beat Russia's Vitalia Diatchenko by two sets to one in the first round of the 2019 French Open in Paris on Monday.
World No.13 Caroline Wozniacki was not as lucky, as she had to succumb a one set lead to lose to Russia's Veronika Kudermetova.
Williams, three times French Open champion dug deep on her experience to win the match 2-6, 6-1, 6-0 to advance to the second round.

The American, currently ranked world No.10, went down 2-6 in the first set, but recovered and won 12 of the 13 games subsequently to secure victory.
The former World No. 1, who as usual made a fashion statement with her outfit, admitted it was not the best of starts for her and was happy to have gone through.
"Those Serena Williams pep talks are really tough," Williams told the Tennis Channel. "I didn't play great in this match. It is what it is. I'm happy I got through it and I knew it couldn't go worse."
Monday's triumph was Williams' 800th career main draw win. She now faces Japan's Kurumi Nara or Slovenia's Dalila Jakupovic in the next round for a spot in the final 32. The two were set to play later on Monday evening.
As she did at last year's competition, Serena's outfit at this competition still made a statement, trading the black catsuit worn last year with a zebra-pattern fabric printed with the words: mother, champion, queen and goddess in French.
Before Serena's win, the French Open had recorded a casuality as Wozniacki failed in her bid to win her first Grand Slam.

Troubled by a naging calf injury, the Dane was unable to on to the 6-0 lead she took in the first first as as she was beaten 3-6, 3-6 in the subsequent sets by the 22-year-old Russian.
Though disappointed by her early exit, the Dane who is yet to win a Grand Slam admitted her injury situation had also affected her fitness.
'Obviously I had a calf injury, so I hadn't really been able to play or practice for some weeks. I played my first points a couple of days ago.
'I played really well in the first set,' said the No 13 seed. 'I played aggressive. I played the way I wanted to play. And then I think she got very lucky in the start of the second set and kind of, you know, took advantage of the opportunities she got.'
'Sometimes you're just unlucky as an athlete. You get hurt, you get injured, and you just have to try to work through that.'
The Dane will now look to stay fully fit and put together some form on the grass ahead of Wimbledon.
'Yeah, my calf now feels good, so that's a positive,' she said. 'I'm going to go back and just practice and work hard and get ready for the grass season.'
