Federer & Del Potro Enjoy Reunion At Formula 1 In Miami
The pair shared a hug before the start of the race, which is held around Hard Rock Stadium, home of the Miami Open presented by Itau.
Federer and Del Potro shared a special ATP Head2Head rivalry, competing in 25 tour-level matches — including six finals — against one another.
Both men have shown an interest in Formula 1 before. Last year, Federer spent time with the likes of Lewis Hamilton and George Russell at the Spanish Grand Prix.
Del Potro, who attended the Miami race last year, caught up with polesitter Sergio Perez on Saturday.
Federer was in the spotlight earlier in the week when he returned to the Met Gala. The Swiss star was joined at the event by tennis players including Serena Williams, Matteo Berrettini and Andy Roddick.
