No Nishikori, no problem as Japan takes commanding lead

Japan grabbed the initiative in its Davis Cup World Group playoff against Ukraine on Friday as Taro Daniel and Yoshihito Nishioka put the home side on the brink of victory.

With World No. 5 Kei Nishikori rested for the opening day's singles following his exertions over the summer, Daniel set the tone by beating an ailing Sergiy Stakhovsky 7-6, 7-6, 6-1 in sweltering conditions in Osaka.

Nishioka then upset Illya Marchenko 6-4, 5-7, 6-4, 7-5 to leave Japan needing to win Saturday's doubles to retain its World Group status next year.

Nishikori, who won bronze at the Rio Olympics before reaching the semifinals of the US Open last week, is scheduled to play in Saturday's doubles in partnership with Yuichi Sugita.

In the second match, Florian Mayer overcame the challenge of Hubert Hurkacz 1-6, 7-6(6), 6-4, 7-6 to give Germany a firm grip on the Davis Cup tie.

Rain delays Davis Cup start in Moscow

The start of the Davis Cup World Group play-off tie between Russia and Kazakhstan has been pushed back to Saturday because of persistent rain, the country's tennis federation chief said on Friday.

"If everything is alright we will play both singles and the doubles," on Saturday, Shamil Tarpischev told the R-Sport news agency.

"If there are delays and bad weather on Saturday, we will continue playing on Monday."

Russia's Andrey Kuznetsov — currently ranked 47th in the world — will now play the opening match at 0700 GMT against Kazakhstan's Aleksandr Nedovyesov.

This is the first time the teams have met in the Davis Cup.
