No nerves from Naomi Osaka in opening round

The four-time major winner and home favourite, Osaka looked to be on good form in her first competitive match in nearly two months.

Osaka last played in the first round of the French Open in late May, before withdrawing from the Grand Slam citing mental health reasons. She then missed Wimbledon.

Although there were slight signs of rust, evidenced by a 59 percent first serve tally, it was very much job done for the Olympic debutant.

Osaka's chances of winning gold at her home games were also helped as Australian Ash Barty, the world number one, crashed out of the women's singles competition after being beaten by Spain's Sara Tormo Sorribes.
