In a sports world filled with scandal, recrimination and bile, Roger Federer's return to the top of men's tennis at the age of 35 represents a refreshingly uplifting tale.
Late on Sunday night, Federer blitzed his compatriot Stan Wawrinka in the final of Indian Wells - the Masters Series event which constitutes the nearest thing to a fifth slam. His statistics are extraordinary in themselves: just 80 minutes for the match, zero sets dropped in the tournament, and already six top-ten wins since the start of the season. Bizarrely, the only loss he has suffered in 14 matches came against the most obscure opponent: world No. 116 Evgeny Donskoy.
But numbers, as ever, tell only part of the story for Federer. You have to watch him to appreciate what he is achieving. Because he has returned from his six-month lay-off with an entirely new weapon: a lethal, high-speed backhand that unleashed a barrage of clean winners against Wawrinka on Sunday night. In backhand-to-backhand exchanges with Wawrinka, whose single-hander had previously been viewed as the best in the world, it was Federer who consistently came off the better.
This is a significant development. Federer's serve, forehand, volley and slice were already world class, but his old top-spin backhand - while undeniably elegant - was never going to intimidate elite players. That has changed dramatically in 2017 and suddenly there are no chinks for the opposition to aim for. Unless he is fractionally off his game - or, perhaps, playing on clay - it is hard to see how you beat him.
The sight of anyone playing top-level tennis at 35 - five years older than Andy Roddick was when he retired - is an anomaly in itself. The Williams sisters - who both have their own health issues - are the only current examples in the women's game. Federer now finds himself in an even stronger position: not just existing at this level, but dominating. On Sunday night, he became the oldest man to win a Masters Series event.
