Live scores Miami Open semi final 2017: Nick Kyrgios v Roger Federer

What a game that was. A true battle with neither giving an inch. Reminiscent of many grand slam finals I've watched over the years.

Kyrgios can take a lot from that. Whether he can build on it is up to him and his mental state, but talent-wise he belongs at the top four level.

Here's the final point as Federer made yet another final and Kyrgios was left fuming at a missed opportunity.

That's all from me. Thanks for following along for what was a belter of a match.

Until next time,

Jamie out.

Kyrgios exits to more boos, jeers and whistles. Uncalled for as he has by and large been well-behaved tonight. Broken rackets are pretty part-and-parcel of modern tennis.

He showed his true potential tonight. Federer is the form player on tour and Nick matched him in every set.

Federer, meanwhile, shows no signs of aging. He will meet Rafa Nadal in the final to write another chapter in their epic rivalry.

Ace.

Kyrgios goes to his number one weapon and goes 15-0 up.

Roger wins his service game to love showcasing his full range of skills and the pressure is back on Nick to stay in this game.

Is another tiebreak looming? 

Will Kyrgios melt down again?

Will I ever get some lunch?

All these questions to be answered after the change of ends.

But if the pressure was on, Kyrgios was not aware. A massive serve in the first deuce point gives him the advantage, followed by a regulation serve-volley to take the game.
