Garbine Muguruza is the first player into the fourth round of the French Open, making it at least that far for the third year in a row.

The fourth-seeded Spaniard played nearly flawlessly while beating Yanina Wickmayer of Belgium 6-3, 6-0 on Court Philippe Chatrier.

Muguruza converted all six break points she accumulated against Wickmayer and had an impressive ratio of 19 winners to only 11 unforced errors.

Muguruza was the runner-up at Wimbledon last year and reached the quarterfinals at the French Open in 2014 and 2015.

Things are looking up for Simona Halep in the third round of the French Open.

The 2014 runner-up has forced a third set against 18-year-old Naomi Osaka of Japan. Halep took the second set 6-2 after dropping the first 6-4.

Halep has had her problems in Paris. Other than that run to the final two years ago, she lost in the first round three times and the second round twice.

Simona Halep has lost the first set of her third-round match to Japanese teenager Naomi Osaka 6-4 at the French Open.

Halep's second serve is letting her down. In the third and ninth games, Osaka pounced on weak second serves to break the sixth-seeded Romanian, who reached the French Open final in 2014.

The set saw five breaks of serve.

Osaka, playing in only her second major tournament, reached the third round at this year's Australian Open.

A loss to the 101st-ranked Osaka would be the fourth time in the last five Grand Slam tournaments that Halep has fallen to a player ranked 70 or below.
