American Marconi Wireless News - Osaka makes triumphant return with three-set San Jose win

The 24-year-old Japanese star outlasted the gritty 19-year-old 6-4, 3-6, 6-1 in a first-round match at the US Open tune-up tournament.

Osaka had not played a competitive match since losing in the first round of the French Open due to a left Achilles tendon injury.

"It's really cool to be back playing," Osaka said after the victory. "I haven't played since May. I didn't know that. Somebody told me that. It's really good to be back."

Former world number one Osaka, whose ranking has slid to 41st, will next play in the second round against the winner of a later match between 18-year-old American sixth seed Coco Gauff, this year's French Open runner-up, and Anhelina Kalinina of Ukraine.

The match marked the return of Osaka's father, Leonard Francois, as her coach. She had been working with Wim Fissette for the past two years.

"It's good for him to be back because he always makes me smile," Osaka said. "It's just good to be back so I'm really happy."

In the first set of her return match, Osaka broke Zheng for a 2-1 lead, saved a break point to hold in the fourth game and held from there to capture the first set after 45 minutes with a service winner.

World number 51 Zheng broke for a 5-3 edge in the second set and held at love on a service winner to force a third set.

Osaka broke twice for a 4-0 lead in the final set, denied Zheng's fightback bid with a second-serve ace on a break point and held for a 5-0 lead.

After Zheng held, Osaka did the same to capture the match on a service winner after two hours and two minutes.

Reigning Wimbledon champion Elena Rybakina of Kazakhstan lost Monday in her first match since capturing her first major title, falling to 12th-ranked Daria Kasatkina.
