NEW YORK-Once the poster girl for the future of women's tennis, Eugenie Bouchard suffered another painful US Open exit Wednesday, even if this time, it was on court rather than the shower room.

The 23-year-old Canadian slumped to a 7-6 (7/2), 6-1 loss to Russia's Evgeniya Rodina in the first round, 12 months after also falling at the first hurdle. "It's one of those matches you kind of want to forget about," said Bouchard. "I know obviously the unforced error count was a bit too high, especially at the end of that first set. Yeah, I just didn't really know what to do out there."

One thing she is definitely doing is pursuing legal action against the tournament hosts, the United States Tennis Association, after she suffered a concussion slipping and falling in the locker room during the 2015 tournament. She was forced to withdraw before her fourth-round tie and won just one more match that season.

Against that bitter background, even Bouchard admitted she was surprised to be given the honor of playing first match on the showcase Arthur Ashe stadium on Wednesday. In many eyes, it was a strange decision for a tie featuring players ranked at 76 and 89. "I'm able to concentrate on the tennis when I'm here, but, I mean, I definitely have bad memories from here two years ago," said Bouchard, confirming that her legal case is still in progress.

It's all a long way from the golden season of 2014 when her girl-next-door looks, easy-going personality and media friendly appearances were lapped up after she made the Wimbledon final and semi-finals at the Australian Open and Roland Garros. But three years on, her career is in freefall after having been ranked at four in the world in 2014.

On Wednesday, Bouchard had chance after chance to impose herself on Rodina. She led 6-5 in the first set and was a break up at 1-0 in the second before she lost six games in succession.The blonde Canadian hit 46 unforced errors in an ugly snapshot of her season so far. "My confidence is not high at all at this point in time, and I definitely had question marks about what my level would be like coming out today," she said.

So far in 2017, Bouchard made the third round at the Australian Open, second round at Roland Garros and was a first-round casualty at Wimbledon. She has just one run to a quarter-final and that came on the Madrid clay, where she downed Maria Sharapova on her way to a season-best performance.

Since the French Open, she has won just two matches on tour. However, she is determined to scale the heights again, a sentiment summed up by the legend on the front of her T-shirt she wore for her news conference. "Why not?"

OSAKA SINKS KERBER AS RAIN CAUSES HAVOC AT US OPEN: Japanese teenager Naomi Osaka sent defending champion Angelique Kerber crashing out of the US Open on Tuesday as torrential rain swept New York, causing more than 50 first round matches to be shelved.

As players ran for cover off the outside courts where just 90 minutes of action was possible, Osaka's big-hitting game and love of the big occasion thrived under the roof of the Arthur Ashe Stadium court. The world number 46, born in Japan to a Haitian father and Japanese mother, won 6-3, 6-1 as sixth seed Kerber became the first US Open women's defending champion to lose in the first round since Svetlana Kuznetsova in 2005.

Osaka, who surrendered a 5-1 final set lead on the same court in losing to Madison Keys in the third round 12 months ago, fired 22 winners as Kerber went tumbling out of the world's top 10 as well as the tournament. Osaka will face either Sweden's Rebecca Peterson or Denisa Allertova of the Czech Republic for a place in the last 32.
