Former world number Naomi Osaka was outclassed in the Wimbledon second round as in-form Emma Navarro eased to a straight-sets victory on Wednesday.

Osaka was unconvincing in an opening-round win over 53rd-ranked Diane Parry before Navarro, the 19th seed at the All England Club, proved too strong on Centre Court.

Navarro never faced a break point in a one-sided showdown, triumphing 6-4 6-1 in just under an hour against the four-time major champion.

The 23-year-old was offered a glorious opportunity in the first set at 3-3 when Osaka fired four straight unforced errors to hand Navarro the advantage.

A poor volley attempt spelt the end for Osaka in the second set as Navarro cruised home in quick time with 16 winners and only five unforced errors.

Navarro has now reached the third round at all three majors this year as Diana Shnaider, who cruised past 2017 US Open champion Sloane Stephens on the same day, awaits for her next clash in SW19.

Data Debrief: Osaka's grass-court struggles persist

Osaka has now never beaten a top-20 player on grass courts in six attempts, with this another reminder of Navarro's ruthless quality.

This was her first appearance on Wimbledon's famed Centre Court, yet Navarro never looked troubled in a routine triumph.

A tougher test will follow in the third round, however, as Shnaider has downed Navarro twice this year, most recently just last week in the Bad Homburg Open semi-finals en route to winning the tournament.
