Federer won his seventh title of the season after he came from a set behind to defeat Juan Martin del Potro 6-7, 6-4, 6-3 and win his hometown event for the eighth time on Sunday (29 October).
The win in Basel saw the Swiss ace earn €395,850 (£352,207, $464,589) as he is now closing in on becoming the first tennis player to win $110m (£83m).
However, reaching that mark will have to wait until the ATP World Tour finals in London that will take place late in November as number-two ranked Federer revealed that he would be withdrawing from the Paris Masters in order to take care of his body.
"I'm really sorry I am not participating in the Rolex Paris Masters this year, but my body needs some rest after the Basel tournament," Federer said, as quoted by the Express.
"I have played a lot of tennis this season and I have to take care of my body if I want to continue playing at the highest level in the years to come. In 2016, it was very painful to miss half of the season, so I learned from it."
Federer's withdrawal has virtually handed long-time rival Rafael Nadal the chance to end 2017 as the year-end world number one.
However, it's not all bad news as the 36-year-old can only continue his career resurgence with a Tour-leading seven titles already this year, with his Basel win being his 95th title, helping him overtake Ivan Lendl to 9th place for most singles titles.

And with $2m (£1.5m) on offer for the winner of the ATP Finals, Federer can have a commanding lead in prize money earned heading into 2018, should he win the event.
