Defending champion Ostapenko upset in French opener

French Open 2018: Venus Williams out but Elina Svitolina progresses

She followed that up losing 6-3 in the second.

Despite notching 28 winners, Williams suffered 35 unforced errors, and also gave best to Wang in terms of points on first and second serves. I didn't expect anything from the match.

Meanwhile, fourth seed Elina Svitolina beat Ajla Tomljanovic 7-5 6-3. She was the first unseeded player in the 50-year Open era to win the women's trophy at Roland Garros.

"I'm the number two seed but it doesn't mean anything as there are a lot of great players wanting to stop me", he said.

The other big story of the day belonged to world No. 182 Mohamed Safwat, who was told he would play his first ever grand slam main draw match on the biggest show court of Roland Garros with just an hour to spare.

Venus returns to Roland Garros for her 21st appearance, still ranked inside the world's top 10 and seeded ninth.

"At times, I do lose maybe a comfort level on the court and confidence, and that's something that I'm still building gradually, obviously", he continued.

Jelena Ostapenko was dethroned as the French Open champion by the 66th-ranked Kateryna Kozlova on the first day of the French Open.

Reigning French Open champion Jelena Ostapenko is out.

Two matches have been left unfinished at the French Open as play was suspended Sunday night because of darkness.

Kozlova, competing with a large, weeping blister on her heel which caused her to take a medical break at the end of the first set, was well worth the victory, playing with power and composure, in contrast to the flustered champion.

The 29-year-old, a two-time Grand Slam semi-finalist, saw off her Chinese opponent 6-4, 6-1 out on Court Six in the sunshine at Roland Garros.

"Having consulted with my team and medical experts it is deemed too risky for me to step out and potentially play five sets on clay especially as I have not played a singles match in almost two months".

"I wasn't at my best, he played with a lot of spin", said the former world No. 1, who dropped serve three times against the 134th-ranked Brazilian.

Instead, the in-form Alexander Zverev, who is seeded second, will be the highest seed in action in the men's singles draw.

The fifth-seeded Ostapenko, who upset Simona Halep in last year's final, lost 7-5, 6-3 against Kateryna Kozlova of Ukraine on Court Philippe Chatrier.

Ostapenko sent shockwaves around Paris and far beyond when she claimed a first tour-level title at Roland Garros past year, but it was a very different story 12 months on. Monfils prevailed 3-6 6-1 6-2 6-1.

"We haven't played in forever", Venus Williams said.

"I have five weeks, so." she smiled.

Dimitrov said he only found out he'd be playing Safwat about 20 minutes beforehand.
