French Open diary: Serena Williams far from best in pursuit of record

Williams arrives in Paris still looking for a record-equalling 24th Grand Slam title having failed to lift a major title since returning a year ago after giving birth to her daughter.

Assuming Williams adequately recovers physically, it is hard to envisage either Kurumi Nara or Dalila Jakupovic ousting her in the second round.

Williams fired four aces in the set but also 14 unforced errors.

The tennis star won her first round match in three sets against Vitalia Diatchenko and after the match, she spoke to Tennis Channel about her new fit.

She produced a see-saw display in an half-empty stadium on Monday, struggling to adapt to windy conditions in chilly weather.

She will certainly hope to complete a second match, something she has failed to do at any tournament since January's Australian Open.

This was just Williams' 10th match in a season hampered by knee injuries, and only her second outing on clay.

Arriving on court in a black and white slogan-covered cape-jacket hybrid (which she removed to play, revealing a black and white printed crop top with matching skirt) immediately after her victory Serena was asked by reporters to "explain her outfit".

In a performance emblematic of a hard season, Wozniacki, a former No. 1 and last year's Australian Open champion, lost in the first round 0-6, 6-3, 6-3 to 68th-ranked Veronika Kudermetova of Russian Federation.

"I just was so frustrated at that point, because I have been training well", Williams said.

Serena Williams is part tennis player, part advocate, part fashion icon no matter where she goes.

Williams has become equally well known for her stand-out court style as much as her sporting prowess in recent years.

Williams' positivity and creative look will return in the second round.

He answered many of those doubts by beating rival Novak Djokovic to win the Italian Open title in Rome, but even that was not enough to convince Nadal that he was ready for Paris.

Nadal's feared forehand was not at its risky best, accounting for more unforced errors (11) than winners (nine).

He said he didn't think he had food poisoning because he felt fine before the match: "Throwing up during the match isn't something that normally happens to me".

After throwing up twice on the court, Frances Tiafoe says he was "very depleted" for the fifth set of a 6-2, 4-6, 6-3, 3-6, 6-0 first-round loss to Filip Krajinovic of Serbia.

"Obviously very depleted and had nothing really in me", said Tiafoe, now 0-4 at Roland Garros.
