At the beginning of the second set we said Anderson's plans had to be to get to a tie-break and give himself a chance to get into the match. He has delivered.

Fed shoots wide with his next forehand. Anderson holds.
This was the Federer lob that had me drooling earlier, brilliant...

Nishikori is going to see if Djokovic beats himself, as his focus is not as laser-like as it was in the first set.

Nishikori is a tough customer mentally. He is probing for a way to get in with the best.

It is still pretty even stevens in the second set. It is good for Anderson to stay into the match after that bad start. He will want to get into the tie-break now.
*Djokovic 6-3 1-4 Nishikori
There's definite tension there. Like a couple you have to go out for tea with their friends after a heated argument. Djokovic takes his seat, picks up a drink and stares straight in front. Ramos looks away to his left, trying to not make eye contact.
Novak has work to do.

A love hold from Kei Nishikori. I think umpire Carlos Ramos might get a word or two from Djokovic here.

Novak Djokovic has an angry rant with the umpire at the change of ends after that warning for bouncing his racquet off the grass.
Is he distracted? Is this a chance for Kei Nishikori?
15-30 on the Djokovic serve.
Federer 6-2 4-4 Anderson*
Seamless from the eight-time champion - wide serves followed by winding winners.
He leaves one though, and a Kevin Anderson return that looked to be dropping long just kisses the chalk.
No bother, Federer holds.
I have scars on my shins from trying this.

Not often these days we hear Roger Federer getting vocal, not like we did in his tempestuous younger days.

That’s when you know it is a big save...
*Federer 6-2 3-4 Anderson
That serve is coming down at some serious speed. Kevin Anderson, at 6ft8, seems to have his eye in now.
A clinical hold to love for the eighth seed.
