The Australian Open 2026 has witnessed a thrilling journey for Alexander Zverev, who credits his serve as the key to his victory over the talented Learner Tien and a spot in the semi-finals. This match-up was a battle of youth and experience, with 20-year-old Tien aiming to make history as the youngest man to reach the last four in Melbourne in over three decades. However, Zverev, the German third seed, showcased a serving masterclass, firing down an impressive 24 aces and committing only one double fault. With a dominant performance, he secured his 10th Grand Slam semi-final appearance, winning 76% of his first-serve points.
But here's where it gets controversial... Zverev's serve was the game-changer, as he saved all three break points he faced with an unreturnable serve. Post-match, he acknowledged Tien's exceptional baseline play, stating, "Learner from the baseline was playing unbelievable. I haven't faced someone with such baseline prowess in a long time."
And this is the part most people miss... Zverev's serve has undergone a remarkable transformation in recent years. In 2020, when he reached the semi-finals in Melbourne and the US Open final, he averaged a staggering 5.9 double faults per match. However, he has consistently improved, reducing his double faults to an impressive 1.9 per match in 2025.
Zverev's journey to the semi-finals is even more remarkable considering his recent injury struggles. Last year, he was a beaten finalist, and in 2022, he tore ligaments in his ankle during his French Open semi-final against Rafael Nadal. This career-threatening injury kept him off the court for six months. But Zverev has returned stronger, feeling "healthy and pain-free" for the first time in over a year.
In the semi-finals, Zverev will face either the world's top-ranked player, Carlos Alcaraz, or the last Australian standing in singles, sixth seed Alex de Minaur. Who do you think will advance to the final? Will Zverev's serve continue to be his secret weapon, or will his opponents find a way to counter it? Let us know your thoughts in the comments!
