A win that proved he has reached a different dimension, a testament to his growth. Alonzo Mourning Jersey . Kei Nishikoris five-set victory over Andy Murray in the quarter-finals of this years US Open was one of the best of his career. Probably one of his biggest since reaching the final in New York in 2014.And it was impressive, coming over four hours and from two sets to one down. But was it, as Japanese tennis veteran Kimiko Date-Krumm suggested, a victory that proved the 26-year-old Nishikori has reached a different dimension? For many the jury is still out.Not that Nishikori has not been successful already. He has won 11 career titles, an Olympic bronze medal, reached the final of the US Open, made three Masters finals, and hit as high as No 4 in the world. But there has been a common theme that seems to have prevented any further progress: fatigue or injury.In the 2014 US Open final he was beaten in straight sets by Marin Cilic, saying afterwards that his body was heavy. After losing in the semi-finals in New York to Stan Wawrinka this year, he said: I was definitely tired, especially in the end. At Wimbledon he did not look fit from the outset against Cilic and eventually retired at 6-1 5-1 down. Nishikori beat Andy Murray at this years US Open There is no doubting Nishikoris talents, but his progression to the very top has been hampered by consistent injury issues. There is also a question of whether he can physically go the distance throughout the two weeks of a Grand Slam.In 2014, one of his coaches, Dante Bottini, said that part of Nishikoris problem with injuries was mental and he didnt really know how to deal with pain and injury.It was a clearly a priority for Nishikori and his team at the time.If I have one goal for next year that would be for Kei to go out there and play 95 percent of the year healthy, said Nishikoris coach Michael Chang in December 2014. To go through the year without having an injury or something happen that takes you out for two to three weeks at a time would be a huge accomplishment and that alone would take his tennis to the next level. Mark Petchey looks ahead to the ATP World Tour Finals Chang also said that he felt Nishikori had an opportunity to win a major on any surface.That challenge, though, has not materialised. While he has performed well at the US Open, he has never made it beyond the fourth round at Wimbledon, has only made one quarter-final at Roland Garros and never progressed beyond the last eight in Melbourne.So what does Nishikori need to do to make the next step up?Perhaps his injuries have just been bad luck. Perhaps he need to lighten his load in 2017 and the years ahead. One aspect that could really help him win a Slam would be his serve Michael Chang I have been playing a lot of matches this year, he said last week. Maybe thats why I have been hurting these couple months, not feeling 100 percent yet.At the moment his body seems as though sometimes it is his toughest opponent.But because of his style of play that might not change. Nishikori does not have a huge serve - of the eight players in London he has the fewest aces in 2016 - and rather he excels with his court coverage and brilliant backhand.But grinding out so many points appears to be taking its toll on the world No 5.Chang admitted earlier this year that one aspect that could really help him win a Slam would be his serve. Michael Chang started working with Nishikori ahead of the 2014 season He added: Its improved a lot over the past couple of years but it still needs to get better and more consistent.Nishikori mixed it up at the US Open by serving and volleying, using the tactic to great effect against Murray in the quarter-finals.Sky Sports pundit Mark Petchey said: Hes definitely trying to protect his serve a bit better this year against obviously great returners.But will that be enough for Nishikori to consistently compete with the best?Ahead of the ATP World Tour finals, he acknowledged: I have to do a little better in the big tournaments, especially the Grand Slams and all the ATP World Tour Masters 1000s.Physically, I got much stronger the last couple of years. I try to work hard every day, try to be confident in every match and enjoy my tennis. Its good motivation.Is motivation enough to see the Japanese make the next step?

Next years tournament is also within sight for Bosnia-Herzegovina, which has never played in a World Cup, but Cristiano Ronaldo looks destined for the playoffs with Portugal after a night when the qualifying picture in the nine groups became much clearer.MALABO, Equatorial Guinea - With Yaya Toure feeling tired and Gervinho suspended, Ivory Coast is still looking to show its best at the African Cup of Nations.The Ivorians have been one of the best teams on the continent for about a decade, but have twice lost in the African Cup final on penalties — to Egypt in 2006 and to Zambia in 2012.This year, the team was put into a difficult group with Cameroon, Mali and Guinea. And in the opening match, the Ivorians were held to a surprising 1-1 by Guinea, with Toure coming off late in the second half.Yaya Toure was a bit tired at the end of the game, so it was better for him to (go) out, Ivory Coast coach Herve Renard said Friday. I expect from him a better second game than the first one he did. This is very important for us. If hes not to improve his level, it will be very difficult for our team.Ivory Coast will next play Mali on Saturday at Malabo Stadium in Group D, while Cameroon will face Guinea in the second match.Toure essentially sat out the teams first two practices in Equatorial Guinea because of fatigue after playing through the holiday season in England with Manchester City. But he was on the field at the start against Guinea in his usual central role.Hes a big competitor, so he will be ready for the second game, said Renard, who led Zambia to the African Cuup title in 2012. Cody Zeller Jersey. .One player who certainly wont be on the field against Mali, or even against Cameroon in the final group match next week, is Gervinho. He was given a two-match suspension after getting a straight red card in the second half against Guinea.Renard dodged questions about how he will cope against Mali without one of his star players up front.We cant replace a player like Gervinho because there is only one Gervinho in Ivory Coast, and maybe in the competition, Renard said. But we have a lot of talent. ... The one who will play to replace Gervinho will do a good game.For Guinea, the draw against one of the tournament favourites brought some positive news to a country deeply affected by the Ebola outbreak.We are not here to send a message or to show anything to anyone, Guinea midfielder Ibrahima Traore said. We are here to play, to qualify for the second round, and to give joy and happiness to the people who are struggling in Guinea.Cameroon is the other favourite to reach the quarterfinals from Group D, but the four-time champion was also held to 1-1 in its opening match, by Mali.Ambroise Oyongo scored in the 84th minute to earn Cameroon a point.You have to respect the fact we only drew, Cameroon coach Volker Finke said, but the second-half performance was not bad at all.
