Nishikori, Osaka give Japan historic tennis day at US Open

Naomi Osaka steamrolled past Ukraine's Lesia Tsurenko 6-1, 6-1 in the US Open quarter-final on Wednesday to enter her first Grand Slam semi-final at the Arthur Ashe Stadium in NY.

Newly minted U.S. Open semifinalist Naomi Osaka grew up on Long Island until she was 9, but tennis fans wouldn't be able to tell that by simply watching her on the court.

Since her Indian Wells triumph, the 20-year-old has produced a much tamer stretch, posting a 13-11 record prior to arriving in NY.

Prior to this meeting, though, it is the first semi-final, between Serena Williams and Anastasia Sevastova, starting at midnight.

"Well, in the mornings I don't play matches, I walk around and hear the lovely honking", Osaka said.

It had taken Williams half an hour to settle into that familiar, chilling rhythm and, once she took the sting out of her opponent's slice, especially on the backhand, she looked more like the player who had taken just 91 games, one surrendered set and six-and-a-half hours to account for five players in this tournament.

Keys and Suarez Navarro met three times previously, with Keys winning all three matches in three sets.

She raced to a 3-0 lead in the first set and then 4-0 in the second against the shaky Tsurenko, who finished with more unforced errors than points in her first major quarterfinal. So she's definitely someone that gets a lot of balls back and something I have to be ready for'.

It was another hot afternoon Wednesday, with temperatures in the high 80s but feeling about 10 degrees hotter with the humidity.

"Long, but not too long", the 13-time Grand Slam victor added. "I wasn't nervous before the match, but as soon as I got into the court, it was different. No matter what happens in any match, semis, finals, I just feel like I've already won".

He is into his third major semifinal, all in NY but is still in search of his initially Slam trophy.

Osaka said: "This moment means a lot".

In New York, members of the Japanese media fill her news conferences after every match.

At night Novak Djokovic will face John Millman for the second time in career. It was odd enough to see a player be allowed to do that during, instead of after, a set, but even odder for it to happen after an even number of games, rather than at an odd-game changeover. He made the best possible start on another scorching hot day in NY by racing through the opening set in 36 minutes.
