A comprehensive analytical breakdown of the stats, streaks, shocks, and storylines that shaped one of the most unusual years in modern tennis.
A Season Defined by Dominance, Breakthroughs, and Chaos
The year began under the shadow of Sinner–Alcaraz supremacy, but it quickly expanded into something far more complex: Iga Swiatek finally conquering grass, Novak Djokovic shattering longevity records, Mirra Andreeva accelerating into superstardom, and outsiders like Valentin Vacherot and Lois Boisson crafting once-in-a-generation Cinderella runs.
The ATP Landscape: Peaks, Valleys, and Unpredictable Turns
Daniil Medvedev’s Season of Contradictions
- 1 Grand Slam match won by Medvedev in 2025 — a five-set survival against Thailand’s Kasidit Samrej in Melbourne.
- USD 76,000 in fines at the Australian Open alone — the largest penalty of his career.
- USD 42,500 in fines at the US Open after a contentious first-round loss to Benjamin Bonzi.
- A six-minute crowd-fuelled pause in that match became one of the season’s strangest spectacles.
- 882 days without a title ended when he won in Almaty — extending another unique streak: 21 career titles in 21 different cities.
Sinner vs. Alcaraz: A Rivalry Flooding the Record Books
- 3-month suspension for Sinner (positive test from 2024), conveniently falling between the Australian Open and Roland Garros.
- 5 hours 29 minutes — longest Roland Garros final in history (Sinner vs. Alcaraz).
- 246 km/h serve by Giovanni Mpetshi Perricard at Wimbledon — new tournament record.
- 0 sets lost by Sinner across the last two ATP Finals — a feat matched only by Ivan Lendl.
- 13–0 — Sinner’s head-to-head domination over Alex de Minaur after the Turin semifinal.
- 6 Grand Slams by age 22 years, 4 months, 2 days — Alcaraz becomes the youngest ever to reach the milestone.

- Valentin Vacherot entered Shanghai ranked No. 204 and left as the lowest-ranked Masters champion ever — also the first Monegasque player to win an ATP title.
- Alejandro Davidovich Fokina went 0–3 in finals this season, falling to 0–5 lifetime.
- Alexander Bublik finished the year at No. 11, winning four titles — half his career total.
WTA Season: Youth Surges, Historic Milestones, and Swiatek’s Contrasts
Mirra Andreeva’s Meteoric Rise
- 17-year-old Andreeva won the WTA 1000 event in Dubai — the youngest ever since the category began in 2009.
- She entered the top 5 at age 18, the youngest since Maria Sharapova in 2004.
- She and Andrey Rublev captured titles 24 minutes apart on the same day — a defining moment for Russian tennis.
Iga Swiatek: Grass, Dominance, and a Curious Split Personality
- 1st career grass-court title at Wimbledon — finally solving her “least favorite surface.”
- 6–0 6–0 destruction of Amanda Anisimova in the final.
- Yet Anisimova rebounded: beat Swiatek twice later, reached the US Open final, qualified for the WTA Finals, and finished No. 4.
