Iga Swiatek celebrates birthday with third round win at French Open

The Polish world number one showed no signs of fatigue following her titanic battle with Naomi Osaka in round two.

The pressure came early and Bouzkova surrendered the first break on a double fault. Just when the first set looked done and dusted though she pegged back one of the two breaks when her opponent served for it. Swiatek was unperturbed and at the second time of asking her weight of shot drew the backhand error and with it, the set.

Despite a slight wobble when serving for the match, Swiatek moved comfortably through to a meeting with unseeded fellow 23-year-old Anastasia Potapova.

"I enjoyed playing today, Marie is a difficult player, she has a really good defence so I didn't want to rush it," said the four-time grand slam winner.

"Honestly I feel good physically. I had a day off yesterday, so I don't feel like this match [against Osaka] kind of stayed with me. Obviously, we'll see at the end of the tournament, but for sure today's match was just solid, so I'm happy that I finished in two sets and I could close it in an hour and 30 minutes. For sure, it's a good thing."

Meanwhile, Sixth seed Ons Jabeur came through a tough encounter with Leylah Fernandez 6-4 7-6 (5).
