Francisco Cerúndolo

Francisco Cerúndolo (Latin American Spanish pronunciation: [fɾanˈsisko seˈɾundolo]; born 13 August 1998) is an Argentine professional tennis player. He has a career-high ATP singles ranking of world No. 18, achieved on 5 May 2025 and a doubles ranking of No. 203, achieved on 31 October 2022. He is currently the No. 1 player from Argentina and South America.

After turning professional in 2018, Cerúndolo made his debut on the ATP Tour at the 2019 Argentina Open, the event at which he later broke through on tour in 2021 after reaching his first ATP singles final and becoming the first qualifier to contend for the title in 20 years. In 2022, Cerúndolo hit several more milestones: emerging into the top 100 in singles, reaching his first ATP Masters 1000 semifinal in Miami in his first Masters main draw, and winning his first ATP title at the Swedish Open, all of which sealed him a year-end top-30 ranking.

At the Grand Slam level, Cerúndolo earned his first wins at the 2023 Australian Open and at the French Open, where he reached the third and fourth rounds, respectively.

Cerúndolo is the older brother of fellow tennis player Juan Manuel Cerúndolo. In 2021, with the Córdoba Open followed by the Argentina Open, the Cerúndolos became the first siblings to reach consecutive finals on the ATP Tour since Alexander Zverev and Mischa Zverev in 2017. In 2022, they also became the first brothers to be ranked inside the top 100 in singles since the Zverev brothers in 2019.
