Daniel Walpole: Strange decision playing Murray yesterday. I had a feeling this will be tough match with Nishikori.
Jiten Chandarana: The Japenese coach took a lot of stick for not picking Kei yesterday, but at the moment, Kei is fresher than Andy.
Jeff Norman: Perhaps now we know why Nishikori didn't play doubles yesterday - Murray is looking exhausted. Selection/tactical issue?

We are going all the way! After nearly four hours on court, Kei Nishikori has got himself level with Andy Murray. Settle in for the decider and maybe even a deciding fifth rubber.

17:02Murray is unloading here, a man with only a few bullets left but determined to take as many with him as possible. Nishikori, though, has found some first serves when he needs them the most. Two sets points...

Former Davis Cup finalist on BBC Two"Nishikori, if he misses any first serves, knows Murray is swinging from hip, going after it and smacking it."

16:58Where on earth has this come from? Murray is playing with freedom and energy, moving around the court like a man who has had a weight lifted from his shoulders. Nishikori will come out to serve for the set, but he's been nowhere in the past two games.

Where has this come from? Put away into open court for one of the breaks back. Murray has got a sugar rush from somewhere. Not to hold and pressure Nishikori once more...

16:54Murray applied some new grip to his handle between games. The operation was delivered with impressive precision considering he's been on court for the best part of four hours. A Nishikori double fault gets is back to 30-30, then a cracking forehand earns Murray a break point...

Former Davis Cup finalist on BBC Two"This is five week lay off. You come up against world number six and no matter how much you train it is not the same.
"Murray's legs have gone. If he can come back from this position it will be one of his greatest achievements."

You haven't got plans for later, have you? The decider is as good as confirmed. Worrying, worrying times for Andy Murray and Great Britain.

16:48This is starting to get silly. Even Nishikori's mis-hits are finding the line. 0-30 on the Murray serve. Lose this game and he can forget the fourth set. Netted forehand. 15-40.

Former Davis Cup finalist on BBC Two“That was an excellent hold. There was a little bit of rhythm back on the serve. It is amazing how you get that energy when you are winning.”

16:45Murray is coming for the Nishikori serve, trying to punish it, but the step in initially results in some ball-to-net. Then the loose forehand, pushed wide in front of a crowd that is in silent disbelief. Nishikori holds.
