Djokovic heat sizzles Federer

Top seed Novak Djokovic saw off a thrilling fight-back by his great rival Roger Federer to reach his sixth Australian Open final and fifth consecutive Grand Slam title match on Thursday.

The Serbian world number one downed third seed Federer 6-1, 6-2, 3-6, 6-3 in two hours, 19 minutes and will face either Andy Murray or Milos Raonic in Sunday's final.

It was the 45th meeting between the two greats with Djokovic now edging ahead of Federer 23-22 in their head-to-head duels.

"These first two sets have been probably the best two sets I've played against him overall throughout my career," declared Djokovic.

"I've had some moments against him in sets where I've played on a high level, but this was, yeah, I think a different level than from before."

Djokovic said he was now going to enjoy his two days off and prepare for his 19th Grand Slam final.

"I think it's good for me at this stage. I've played a lot of tennis. Actually it's going to serve me well for my recovery," he said.

The amazing Serb continued his recent domination over the 17-time Grand Slam champion and on Sunday, he will become the first man in the Open era to contest six Australian Open finals.

It will also be Djokovic's 19th Grand Slam final overall and he moves into equal-third place with Ivan Lendl on the all-time list of most appearances in major finals, which is headed by Federer.

The 10-time Grand Slam champion was in sensational form in the opening two sets, carving up Federer in their 15th Grand Slam encounter with his fabulous groundstrokes for the loss of only three games in just 54 breathless minutes.

He broke Federer's first service to 15 and then held his serve to lead 3-0, winning 12 of the first 14 points.

The Swiss third seed was broken again in the sixth game, netting a forehand with Djokovic in full cry.

Djokovic's 6-1 first set was his easiest opening-set win over Federer. He won 24 points to 11, with the rushed Swiss making 12 unforced errors.

An imperious Serena Williams set up a crack at her seventh Australian Open title by trampling Agnieszka Radwanska, with only Angelique Kerber now capable of stopping her equalling Steffi Graf's Open-era record of 22 Grand Slam triumphs.

The dominant top seed was in inspirational form as she pummelled the Pole 6-0, 6-4 on Rod Laver Arena, with the stunned fourth seed calling the opening set the best tennis she had ever faced.

It set Williams up for a 26th Grand Slam final as she zeroes in on a seventh Australian Open title and a bid to match's Graf's record. Margaret Court holds the all-time record of 24 major wins.

Germany's Kerber, the seventh seed, earned her right to face Williams by beating unseeded Briton Johanna Konta 7-5, 6-2 to sweep into her maiden Grand Slam final.

It marked the first time a German has reached the final at Melbourne Park since Anke Huber in 1996, but Kerber faces a monumental task with the American powerhouse across the net in Saturday's decider.

Williams, 34, has a 5-1 win record against Kerber and vastly more big match experience, but she is not underestimating the threat she faces.
