Greg Rusedski and Peter Fleming have questioned whether or not Britains war horse Andy Murray can physically recover from his epic match with Milos Raonic in time for Sundays ATP World Tour Final. Murray remains on course for a dramatic showdown with Novak Djokovic as the world No 1 fought with gritted teeth and weary limbs to stage a dramatic fightback to defeat Raonic in the semi-finals. Watch NOW TV Watch Sky Sports for just ￡6.99. No contract. The match lasted 18 minutes longer than his marathon victory over Kei Nishikori in the round-robin stage just four days earlier. Now only a 24th straight win will bring the golden end to his remarkable season, and although former British No 1 Rusedski admits it will be hard, he feels Murray will find a way to lift himself for the final. Murray was thrilled to come through against Raonic in the longest match ever at the season-ending tournament It was an absolutely brilliant that third set from Murray in the way he digs deep and finds a way to get the job done, Rusedski told Sky Sports.He breaks another record - 23 matches in a row. Its hard enough doing 10 in a row, but 23 and also against the very best players on the planet. I mean, Raonic was exceptional, he really raised his game.But now Murray must show that belief, that desire to come through. He wants to be year-end number one and we have the dream final possibly happening tomorrow. Murray wins O2 marathon semi Andy Murray beats Milos Raonic in ATP World Tour Finals last four Hes got to get into those ice baths and recover. Hes got 24 hours to get ready, but he will be so motivated. I was so impressed - that was one of his greatest performances ever to come through that in three hours and 38 minutes because he had to be tired in that third set.Mentally it is going to be tough for him because hes going to be sore, hes going to be tired and hes got to find a way to lift himself. This is where the experience of coach Ivan Lendl comes in, who has been through these situations before. Murray pulled off this magnificent half volley during the second set tie-break Murray has now played two three-hour monster matches and will be back on court on Sunday evening and Fleming thinks its asking a lot.As usual Andy seems to come up with his best responses when his back is against the wall and it most certainly is now, said former doubles specialist Fleming.Lets face it, hell need to come out quickly and establish himself and hopefully ride the wave.

I was just trying to stay in there and hang in there.Kuznetsova was the final player to earn a berth into the eight-player, year-end championships when she defended her Moscow title Saturday.The Russian arrived in Singapore on Sunday afternoon after a grueling four weeks of chasing a spot in the WTA Finals for the first time since 2009. She played three tournaments in China ahead of taking a wild card into the Moscow tournament.In a bizarre move while trailing 1-2 and down a break in the third set, Kuznetsova took a pair of scissors to the back of her head and cut off a portion of her braid during the changeover.It was bothering me a lot, said the Russian, who asked the umpire to have scissors brought to the court. When I was hitting forehands, every time I would hit a good shot, it would hit my eye.ddddddddddddShe added: I thought, OK, whats more important now, my hair, which I can let grow, or the match?Kuznetsova broke Radwanskas serve after the impromptu haircut, but after dropping her serve again in the fifth game, she cried into her towel on the changeover.Still, trailing 2-4, Kuznetsova refused to surrender and climbed back into the set.The hair Kuznetsova chopped off remained on her chair for the remainder of the match.The drama continued in the second match, when Karolina Pliskova, who was up by a set and a break, came back from 2-5 down in the third set to defeat Garbine Muguruza 6-2, 6-7 (4), 7-5.Muguruza had one match point at 5-2, 40-30, but couldnt close down Pliskova, who won 20 of the final 24 points.Im very happy that I made it, said Pliskova, making her WTA Finals debut this week in singles and doubles. This doesnt happen every day.Kuznetsova and Pliskova stand at 1-0 in White Group action, while Radwanska and Muguruza are 0-1. ' ' '
