Legend McEnroe sees a new dawn after Sinner joy

- NEIL McEMAN

JOHN MCENROE has declared "the official changing of the guard" in men's tennis after Jannik Sinner and Carlos Alcaraz secured all four Grand Slams this year.

And Italian Sinner, the world No.1, welcomed the "new generation" taking over the sport with "new rivalries" after decades of domination by the Big Three.

Australian Open champion Sinner, 23, became the youngest man to complete the calendar hardcourt double by beating Taylor Fritz in the US Open final.

And with Alcaraz, 21, winning the French Open and Wimbledon, it is the first time since 1993 that all four Majors in the same year

have been won by players aged 23 or younger.
