Mektic shows he's also a natty volleyer - making two on the trot to take the pair to 40-0.

Jamie Murray is known for his net play now, everyone is studying the way he does it as he moves so well, takes the pressure off his partner and makes his presence felt. Little shimmies with the shoulders, fake shimmies, trying to catch the eye of the opponent.

They hold as Barbora Krejcíkova goes long with a forehand.

Players are always superstitious - Jamie Murray had a baseball cap on the other night too and they like to keep things going.

Murray seems to go from strength to strength. When he decides he's had enough of tennis he will look back and think, 'what a career'.

BMS does a great job at the net to move the duo to 30-15 before Mektic comes out on top in a volley-duel.

They are probably favourites but no guarantees they're going to win. Murray is very imposing at the net - and he has a left-handed serve which goes a long way.

He chips, lobs He's a very cunning doubles player.

His reflexes are great. The pair have fun together and are very good volleyers.

Is Jamie Murray set to win his eighth major? If so he will become Britain's most successful Grand Slam player of the Open era.

The pair that stand in the way of both he and partner Bethanie Mattek-Sands are fifth seeds Barbora Krejcikova from the Czech Republic and Croatian Nikola Mektic.

Murray said: "We lost to them last year in a tough match so we had the bit between our teeth today, the chance for a bit of revenge. There was a lot on the line. For us to be in the final is really exciting."

Those eight double faults were so costly for Garbine. To lose a Grand Slam final on a double fault is absolutely horrible. At the end the points difference between the two was huge - 15 points. Kenin was more composed of the two. After that first set she changed her game to play on the angles. She made Garbine physically work.

She showed so much fighting spirit and that took her to the trophy.

And now for the champion, Sofia Kenin: "OK! This is my first speech, but I am going to try my best. I want to congratulate Garbine on a great match, I am sure we will have more great finals in the future.

"I want to say my dream has officially come true! I cannot describe this feeling, it's so emotional, i am so grateful to stand here - dreams come true, so go for it, if you have a dream it is going to come true.

"It is such an honour and privilege to be here. Thank you so much. I would like to thank the crowd, this past two weeks has been the best of my life!

"And last but not least, my team, my dad, thank you for making this possible - I can't believe we are here today, we worked so hard. My mum, back home probably watching, so I love you mum! We really worked hard and I am so grateful for this. Thank you so much."

More from Australian Open runner-up Garbine Muguruza: "A fantastic match, Sofia, I think we are going to see you play many more finals, for sure.

"I have to say thank you to my team, they were out there suffering with me today.

"It has been incredible playing out here in this environment, the crowd is what makes it special - we play for you guys, so thank you for coming."

Garbine Muguruza makes her way up to the podium, looking understandably deflated.

A fantastic run from the unseeded Spaniard, but just not to be.

"Oh, ok..." she says. "I'll keep it short because I'm going to get very emotional."
