Alcaraz takes the first set 6-4 as Zverev fumbles at the finish line! The German gifted the crucial break to the Spaniard with a costly double fault. Alcaraz then held to love with clinical ease to claim the early advantage. It's 1-0 to Carlitos!

Zverev fails to capitalise on Alcaraz's first double fault of the match. The Spaniard resets to put together a run of four points. Makes it 4-4

Finally! Ace number 81 for Zverev. It couldn't have come at a more crucial time after Alcaraz earned a break point with a magical forehand winner. The German stood tall under pressure to erase the threat and hold his serve. He leads 4-3 in the first!

Interestingly, we've seen three aces so far from Alcaraz, while we are yet to see a single one from Zverev today. That's a major surprise considering the German leads the tournament with 80 aces coming into the semi-finals.

Zverev and Alcaraz aren't giving an inch to one another. It's 3-3 in the first set. The Spaniard had to grind it out again after gifting the opening point to Zverev, but he stayed composed to level the score.

Zverev's forehand lands just outside the tramline, allowing Alcaraz to level the score at 2-2 in this opening set. Clinical serving from the Spaniard so far; he isn't giving Zverev any room to breathe on the return.

Much better from Zverev as he holds to love to make it 2-1 in this first set. He got it done in under two minutes, topping the game off with a clinical, accurate forehand. It's been strictly neck and neck so far-neither man giving an inch!

Alcaraz holds to 30! A solid start to the set from the Spaniard. He opened the game with a clinical ace before racing to a 40-0 lead. A brief lapse allowed Zverev to claw back to 40-30, but the Spaniard nails another ace to himself a quick sigh of relief. It's 1-1.

And we are underway at Rod Laver Arena! A shaky start from Zverev, but he manages to hold at 30. His first-serve percentage was hovering at just 50% in that opening game, looking a bit wayward early on. However, a loose error from Alcaraz hands the German the opening game of the match.

Alcaraz and Zverev are in the middle, doing their pre-match warm ups. It is worth mentioning that Alcaraz is yet to drop a set in Melbourne this year. However, John McEnro feels Zverev has "got a shot at it (beating Carlos Alcaraz), for sure."

A fourth consecutive Slam final between the new 'Big Two'-Carlos Alcaraz and Jannik Sinner-is on the cards in Melbourne. Sinner, chasing a historic third consecutive Australian Open title, faces 10-time champion Novak Djokovic later today. With the first semi-final at Rod Laver Arena just moments away, the atmosphere is electric!

Alcaraz and Zverev have met 12 times previously, with both winning six matches each. The Spaniard was full of praise for his opponent after beating Alex de Minaur in the quarterfinals.

"I have seen him throughout the whole tournament and I know he is playing great, aggressive tennis," Alcaraz said.

"I have to be ready, not just me but my whole team as well.

"We need to play tactically really well, it's going to be a great battle."

The Australian duo of Olivia Gadecki and John Peers made it two-for-two, clinching the mixed doubles title for a second consecutive year in Melbourne. They defeated Austria's Lucas Miedler and Vera Zvonareva 6-3, 6-2 in straight sets. This victory marks John Peers' fourth Major doubles title and continues Gadecki's ascent as a hometown hero at Melbourne Park.

The German Zverev made the final last year and was thumped by Sinner before his season was blighted by shoulder, back and ankle injuries. But he is pain-free and with a newly aggressive approach could pose a threat. Zverev famously dismantled the Spaniard on this very court in 2024 and is himself hungry to banish the ghosts of three previous Grand Slam final defeats.

Alcaraz is on his own mission -- to become the youngest man to complete a career Grand Slam of all four majors aged just 22. Rafael Nadal did it at 24. He has been in ominous touch so far in Melbourne, but faces a tricky challenge in the form of Zverev, who is still seeking an elusive first major crown at the age of 28.
