Carlos Alcaraz vs Alexander Zverev Tips, Prediction & Live Stream - Alcaraz to face first real test in semi-finals

Alcaraz is chasing a piece of tennis immortality over the next few days, aiming to become just the sixth man in the Open Era to complete the Career Grand Slam, joining Andre Agassi, Roger Federer, Rafael Nadal, Novak Djokovic and Rod Laver. If Alcaraz is successful this tournament, he would be the youngest player in the Open Era to complete the feat. The Spaniard has already broken new ground in Melbourne, reaching his first Australian Open semi-final without dropping a set - including a straight sets demolition of sixth seed Alex de Minaur in the previous round. Meanwhile, Zverev has looked stronger with each round this tournament was was impressive in beating the in-form Learner Tien in the last eight, firing 24 aces and winning 106 points to 68 in exchanges that went between 0-4 shots - illustrating a clear intention to play aggressive, first-strike tennis.

Zverev will need to adopt a similar strategy if he to have any chance of upsetting Alcaraz and I think he can make this match competitive - if he maintains his current level. The German has had success against Alcaraz in the past, but he will need to serve out of a tree - which he can easily do. I'm backing Over 36.5 total games as the best bet for this semi-final, but Alcaraz is playing magical tennis and he just has more strings to his bow. Zverev's horror record vs top five players at the majors also can't be ignored. Will take the top seed in four.

It was a stellar season for Alcaraz last year, with the Spaniard capturing eight titles - including Roland Garros and the US Open, with those results contributing to him finishing the year as World No. 1.

The Australian Open was the one slam that Alcaraz had found challenging in his short career, but he's been brilliant over the last fortnight and isn't showing any struggles after ending his time with Juan Carlos Ferrero.

Alcaraz cruised past the unseeded Adam Walton and Yannick Hanfmann before crushing Corentin Moutet for the loss of just seven games. The 22-year-old then raised his level for the R16 against Tommy Paul, surviving a tough opening set before closing it out in straights.

Continuing his persuit of a seventh major title, Alcaraz broke new ground in Melbourne on Tuesday night, dismantling home hope Alex de Minaur 7-5 6-2 6-1, becoming the eighth Spanish man to make the Australian Open semi-finals.

It was a relatively quiet and disappointing season for Zverev in 2025 - he only managed the one title and once again suffered Grand Slam final heartbreak at the Australian Open, while he also blew a golden chance to rise to World No. 1 during Jannik Sinner's three-month suspension.

Zverev was also dealing with some niggling injuries throughout the year, compounding his struggles.

However, the German looks back to some of his best tennis at this tournament, especially in the last couple of rounds.

Zverev dropped a set in each of his first three rounds against Gabriel Diallo, Alexandre Muller and Cameron Norrie before raising his level for Francisco Cerundolo - a player who has beaten him multiple times in the past.

Last year's runner-up maintained that high level for Learner Tien, who was coming off a straight sets blitz of Daniil Medvedev. Zverev shot down 24 aces and was able to dictate early in baseline exchanges to secure the win in four sets, clinching the fourth-set breaker with some aggressive ball-striking.
