The victory on Sunday made him the highest earning player in sport on this measure, according to Forbes, and that will naturally extend with each win this week.
Off-field earnings for star players often dwarf the on-field rewards of their sport, but Federer arrived at the O2 Arena having amassed an incredible $109,853,143 in prize money nonetheless.
He then added $191,000 for the Sock win and $105,000 from a participation fee, which the ATP confirmed is counted as prize money.
That brought Federer’s total to $110,149,682, while Tiger, after controversy and injury sparked a slide he may never fully recover from, has won a “mere” $110,061,012.
The next highest earning tennis player is Novak Djokovic, whose career winnings total $109,805,403. Rafael Nadal is a relative poor relation after that, not yet reaching nine figures; the last Big Four member, Andy Murray, is fourth among them, with career prize money just shy of $61 million.
There was more on offer for 36-year-old Federer here, too. He was due another $28,000 appearance fee for facing Alexander Zverev on Tuesday night and the winner of that match will earn a $191,000 prize; semifinal triumphs at the finals earn $585,000, and the final bounty is $1.2 million — with a bonus for any player who can go undefeated through the tournament.
A lot of players and pundits have been pointing out this week that is a long, hard season at the top of tennis. It’s a pretty lucrative one, too.
Will Uncle Toni stay on Rafa’s team?
Amid all the hullaballoo surrounding Nadal’s withdrawal from the finals through injury, the departure of coach Toni Nadal from the world No. 1’s team passed by almost unacknowledged.
The Spaniard’s painful defeat to David Goffin on Monday signalled the end of his season, and the point at which his uncle planned to step down and concentrate on academy work.
