London: Andy Murray has been told he is “required” to compete in the ATP Tour Finals after the Scot discussed skipping the event to prepare for the Davis Cup final.

After helping Great Britain reach a first Davis Cup final in 37 years by beating Australia, Murray suggested he might miss the hard-court ATP Tour Finals to prepare for the Davis Cup showpiece, which is expected to be played on clay.

But although the Davis Cup final begins on November 27, just five days after the ATP Tour Finals conclude, ATP president Chris Kermode expects Murray to be present at London’s O2 Arena.

“The Barclays ATP World Tour Finals is a mandatory event on the ATP World Tour and all players who qualify, unless injured, are required to compete in the event,” Kermode said in comments quoted by several British newspapers on Tuesday.

“He has had a fantastic season and earned his place among the world’s top eight players to compete at the season finale. We are aware of the comments made after the Davis Cup tie in Glasgow, however our expectations are that, if fully fit, Andy would compete in this year’s tournament.

“Unless we hear otherwise via an official withdrawal, he is still entered to compete at the O2.”

Murray, 28, had told BBC Radio 5 live: “The O2 would obviously be a question mark for me if we were playing on the clay. I would go and train and prepare on the clay to get ready for the final.

“For me to play — if I was to reach the final — five in a row and then take a couple of days off, it would mean only playing for two days on the clay before the Davis Cup final starts and that wouldn’t be enough for me.

“I need more time on the clay to let my back get used to it.”

Murray has a history of back problems and revealed after the semi-final win over Australia that he had struggled with a back injury during the tie.

Meanwhile, Carla Suarez Navarro ended her eight-match dry spell with a hard-earned 7-6 (7/3), 6-2 victory against Kateryna Bondarenko at the Pan Pacific Open in Tokyo on Tuesday.

It was the first victory for the 10th-ranked Spaniard since June and she suffered a first-round, straight-set defeat against the 83rd-ranked Bondarenko a week ago at the Japan Women’s Open Tennis.

Suarez Navarro said that defeat gave her the insights to gain victory Tuesday against the Ukrainian.

“It’s true that I lost (a week ago). But I had much in my mind how to play against her,” Suarez Navarro said.

“Today I just tried to play and be relaxed. I tried to play my game.”

Suarez Navarro said she had “lost confidence” as she kept losing match after match, with the negative feeling leading to psychological fatigue and more losses.

Now she hopes to regain her form as the current season draws towards its close, with only a handful of Asian tournaments to go.

“I feel happy because I can change the situation. With the next match, I have one more opportunity to try to play my game, and try to play like the beginning of the season,” the Spaniard said.

In other matches German fifth-seed Angelique Kerber crushed Daria Gavrilova of Russia 6-2, 6-2.

It was Kerber’s first appearance since her nail-biting US Open third-round showdown against Victoria Azarenka, when she lost but won much praise for her performance.
