The Swiss skipped the entire clay court season in 2017 and 2018 and a year ago played only two tournaments on the surface before arriving in Paris for the French Open.
It was speculated that Federer would include the Masters of Madrid and Rome in his calendar for 2020, but his agent, Tony Godsick, said that will not happen. "It's just going to get to Roland Garros to play, and there is no other graveltoernooien on it".
The 38-year-old Swiss is playing in the last few years, however, the tournaments, and, in particular, graveltoernooien.
Federer was the semi-finalist at Roland Garros a year ago before wasting two match points in the final at Wimbledon and advancing into the last four at the Australian Open a couple of weeks ago, losing only to Nadal and Djokovic in those three encounters.
The Miami Masters hard court tournament from March 25 to April 5 is the last step on your calendar before Paris.
He will though play at the Dubai Duty Free tennis championships next week followed by the BNP Paribas Open in California next month.
While Federer has gone seven straight Grand Slams without adding to his collection, he said in Melbourne he still thinks he can win more. "Yes, I do believe that", said Federer.
Nadal won that one 6-3, 6-4, 6-2 en route to his 12th Major on beloved clay, with Federer waiting for another chance of chasing the trophy in Paris, winning it only once in 2009 when he completed a Career Grand Slam. They next meet the winners of the quarterfinal between Jan-Lennard Struff-Henri Kontinen and Jamie Murray-Neal Skupski.
