Thiago Agustin Tirante About

The La Plata dirt-baller who turned a junior No. 1 ranking into a top-50 floor

Thiago Agustin Tirante is an Argentine right-hander out of La Plata, born in 2001, and his roots run as deep as any on tour — he began playing tennis at his grandfather's club in La Plata as soon as he could walk at nine months old, coached by his aunt, Vanesa, who taught him to play. He earned his first ATP ranking point at age 16 in 2017, and ended 2019 as the No. 1 junior in the world, sweeping his last 18 matches en route to three titles in as many weeks at Yucatan Cup, Eddie Herr and Orange Bowl.

The game is built on clay, the way the résumé suggests. Over his career at ATP level he holds a 20-15 record on clay against 4-6 on hard, and the heavy forehand — his favourite shot — anchors a patient, grind-it-out baseline identity rooted in second-serve return depth and break-point resilience. He's not a big server by tour standards, but he's added pop: he's averaging 6.4 aces per match over the last 52 weeks, up from a career 5.0. The idol is fellow Argentine Juan Martín del Potro, and the aspiration tracks.

The breakthrough came at the 2024 Nordea Open in Båstad, where he reached his first ATP Tour semifinal after beating defending champion and No. 8 Andrey Rublev in the second round for his first top-10 win, before losing to eventual champion Nuno Borges. He'd already logged his first slam win at the 2023 French Open as a qualifier. He cracked a career-high No. 58 in May 2026.

The current beat is the deepest slam run of his life: at Roland-Garros he came through two five-setters, including a win over Alejandro Davidovich Fokina, before falling to Pablo Carreno Busta in another four-set grind in the third round.
