And he was the loser of the match, which was played over three days and lasted a record 11 hours and five minutes.
Winner John Isner stands to earn at least $2,000 an hour, since the win earned him a spot in the next round, and presuming that his next match doesn't last an extraordinarily long time.
That sounds like great pay. Of course, it doesn't account for the hours of unpaid training and practice that pro players must put in, the costs of travel, coaches, and so on.
Players within the top 200 can expect to make money from clothing and racquet sponsorships in addition to prize money.
But to make a good living at professional tennis, players have to break into the top 50, according to The Tennis Times.
Since the Isner-Mahut marathon occurred in the first round, Mahut exits with £11,250 (about $16,800) that all first-round losers receive. But he ought to receive something more.
His tireless effort over three days and 183 games brought more attention to lowly Court 18 of Wimbledon and created more history than all the other first-round matches combined.
And what of Isner, the 23rd seed who finally broke Mahut's serve in the 138th game of the decisive fifth set? All his upcoming opponents should agree to run 10 miles right before they meet him on court.
His endurance and ability to keep serving aces, despite obvious fatigue, are worthy of nothing less.
Years from now, tennis fans will probably remember this match more than the championship.
Incidentally, the winner of the men's singles title will walk away with £1,000,000 (nearly $1.5 million). If his matches last an average three hours, that works out to $71,400 an hour.
Now that's real money.
