The Australian Open men's semifinals feature a historic lineup with Carlos Alcaraz, Jannik Sinner, Alexander Zverev, and Novak Djokovic all advancing. For the first time since 2013, the top four seeds have reached this stage, setting up thrilling potential matchups.

Alcaraz, the No. 1 seed, is on a remarkable run, having won all 15 sets played so far. His serve, modeled after Djokovic, is proving to be a formidable weapon, with a 76% success rate on critical points. A win would make him the youngest player to complete a career Slam.

Sinner, the No. 2 seed, is a favorite, having won three of the last four hard-court major finals, including the past two Australian Opens. His efficient serving and minimal errors have marked his journey, with a record of 32 wins in his last 33 matches on hard courts. A win against Djokovic would set up a potential final against either Alcaraz or Zverev.

Zverev, the No. 3 seed, seeks his first Grand Slam title, having reached three finals, including last year's Australian Open. His disciplined play and powerful serve have been key, landing 80 aces with only six double faults. He holds a balanced record against Alcaraz, standing 6-6 in their encounters, offering a chance for an upset.
