NCAA singles champion for UCLA
Marcos Giron was born in Thousand Oaks, California, in 1993, to Argentine and Ecuadorian parents. He played for UCLA from 2012 to 2014, alongside Mackenzie McDonald, and won the NCAA singles title in 2014 before turning professional. Operations on his right hip in December 2015 and his left in February 2016 dropped him below No. 750 by October 2016; while he recovered he worked as a volunteer assistant coach at UCLA.
It took him about four years to break into the top 100, which he did in 2020. He reached his first tour semi-final in Sofia in 2021, made the third round of the French Open in 2021 and 2023 and the Australian Open in 2025, and played the Tokyo Olympics. After losing his first two tour finals, at San Diego in 2022 and Dallas in 2024, he won his first title on grass at Newport in July 2024 and rose to a career-high No. 37 that August.
As of November 2026 he has one ATP singles title and is ranked 88th by the ATP.

2015 to 2016
Giron had surgery on his right hip in December 2015 and his left in February 2016. When David Goffin lost to him in Antwerp in 2020 and heard about the operations, he said: "You couldn't see that he had surgeries, so I think he had a good surgeon."

Giron travels with a PlayStation. In the 2020 US Open bubble he played Fall Guys with Mackenzie McDonald, Taylor Fritz and Tommy Paul, and judged that "Fritz is definitely the strongest on the sticks."

Andre Agassi, Giron's childhood idol, had helped him with his game since they met about four years earlier. At Newport Agassi asked him: "Hey dude, any chance you have an extra seat in the box today?" Giron said afterwards that without Agassi he did not know if he would have won a title.

To the 19-year-old Michelsen, Giron said: "He's got such a bright future. I'm happy to get the win now while I can!"
