Wimbledon 2019: Wayward Naomi Osaka sent packing in straight sets

Naomi Osaka crashes out of Wimbledon first round in straight sets

The opening day at Wimbledon on Monday saw its biggest upset when second seed Naomi Osaka's bid to win a third Grand Slam title came to a premature end as she lost to Kazakh Yulia Putintseva, 7-6 (7/4), 6-2 in the first round.

Facing Yulia Putintseva, a two-time French Open quarterfinalist who is now ranked No. 39, on Centre Court, Osaka started strong and took a 3-1 lead but ultimately lost the set in a hard-fought tiebreak.

The 39-ranked Putintseva won her previous two encounters with Osaka - most recently in Birmingham last month - and sent the world number two packing on Centre Court.

Later, 15-year-old American Cori Guaff caused one of the biggest shocks in Wimbledon history by dispatching Venus Williams 6-4 6-4 in the first round.

Anderson will now play Serbia's Janko Tipsarevic who registered his first win at the tournament in seven years when he defeated Japan's Yoshihito Nishioka 6-4, 6-7 (2/7), 6-2, 5-7, 6-2.

This was the first time Putintseva had played on Wimbledon's Centre Court.

"I've said this before: I want to be the greatest".

McEnroe suggested it is things like this that may have "distracted" Osaka from her main job, playing tennis, because "she's probably got a lot of offers, opportunities", away from the court. "I slid a little bit and felt a little bit of pain behind the knee and the foot", Halep said.

Naomi Osaka was eliminated from the Wimbledon Championships on Monday, losing to Yulia Putintseva in the first round.

The seventh seed fell to a five set 6-4, 3-6, 6-4, 6-7, 6-3 defeat to Italy's Thomas Fabbiano. "I just hope that it's sooner, rather than later". Osaka and Putintseva have now met three times, and Putintseva has beaten Osaka each time.

Having only reached one semi-final since lifting the Australian Open trophy in January, the coming weeks will lead to head-scratching analysis from Osaka as she tries to rediscover the missing ingredients from her game.

Osaka looked increasingly despondent in the second as the unforced errors came thick and fast.

"But it just looks like right now it's one of those tough times".

Williams had won four of her seven Grand Slam titles by the time Gauff was born.

"I think it's very possible Ash Barty wins her second grand slam here, and her second in a row", she said.

"I have never played on this court, in fact, I have never been on it".

But it's factors beyond groundstrokes and serves that are likely to receive most of the attention as observers dissect what's gone wrong for the 21-year-old over the past five months.
