Nadal baffled by Olympics no-shows

Rafael Nadal knows only too well what it's like to miss out on playing at the Olympics, so he doesn't understand why so many of his fellow tennis pros are turning their backs on the Rio Games.

When injury forced the 2008 Beijing gold medalist to withdraw from the 2012 London Games, he described it as "one of the saddest moments of my career".

No wonder he finds it baffling the likes of American John Isner, Australian Bernard Tomic, rising Austrian Dominic Thiem and fellow Spaniard Feliciano Lopez have chosen to skip Rio in August.
