Marcos Giron is an American professional tennis player who was born on July 24, 1993, in Thousand Oaks, California, United States. Born to Argentine and Ecuadorian parents, Marcos started playing the sport from an early age, thanks to the influence of his mum.
His talent was harnessed early on, with him going through the US college system in order to hone his skills and earn his place on the ATP Tour. After a successful junior career, Giron was keen to try his luck on the main tour.
Following years of hard graft, the American earned his first chance at glory on the ATP Tour when he got his main-draw debut at the Winston-Salem Open in 2014. One cannot say he did not earn his debut appearance, with him having to battle through three qualifying rounds to set up a first-round main draw tie against Aleksandr Nedovyesov.
Giron would have hoped that, despite ultimately losing in the first round, this appearance would have acted as a springboard for future appearances and, therefore, performances on the ATP Tour, but it did not work exactly like that.
The following few years were still spent on the ITF and Challenger tours, with him occasionally dabbling in ATP tournaments. 2019 was when his luck started to change. At the ATP Masters 1000 event in Indian Wells, the American got through to the third-round after seeing off opposition such as Jeremy Chardy and Alex de Minaur.
Later that season, he saw his Grand Slam main draw debut at Wimbledon before backing that first-round performance up with direct entry into the US Open. He would have to wait another whole year before he was to get his first victory at that level, though, with his first Major win coming at the 2020 US Open.
Another year down the line, Giron had reached the third round of a major for the first time in his career at the 2021 French Open. Progress continued this upward trend into the next season, with the American reaching the deeper rounds at the ATP tournaments.
Seeded third at the San Diego Open in 2022, the American reached the final after a stellar run, not dropping a set and seeing off opposition such as Daniel Evans en route.
