Rafael Nadal, then 18, had already won four titles by the fifth month of the 2005 season. Nadal extended his meteoric rise through the rankings by winning his maiden Masters 1000 title in Monte Carlo.
Instead of being satiated or fatigued after such a fantastic result, Nadal was hungry for more within a week.
For his maiden Barcelona Open championship, the young gun defeated longtime Roland Garros champion Juan Carlos Ferrero 6-1, 7-6, 6-3.
A few weeks ago in Valencia, Nadal defeated a former world number one 6-2, 6-1 in under an hour.
He had to work much harder in Barcelona, winning in two hours and 56 minutes.
The teenager saved eight of nine break chances and stole the opponent's service four times out of eleven break chances.
As a result, he won in straight sets and began his remarkable streak at one of the world's oldest events.
Rafa found himself in the top-10 for the first time the following day after claiming 800 ATP points in Monte Carlo and Barcelona, making this achievement even more significant for him.
