Back in 2004, Rafael Nadal was just a spirited teenager, taking the opportunities as they came. He agreed to take part in a swim with the dolphins ahead of the Miami Open.

That year, a 17-year-old Nadal faced off against Roger Federer for the first time, stunning him 6-3, 6-3 in the third round. The following year in their second-ever meeting, the Spaniard would lose to Federer in the final (in his first of five Miami Open final losses).

The pair have faced off a total of 37 times during their long careers, including in this year's Miami Open final (which Federer won for his third title of 2017).
