Spanish teenager Carlos Alcaraz claimed the first title of his career as he beat Norway's Casper Ruud to become the youngest winner of the Miami Open.
Alcaraz overcame a slow start to win 7-5 6-4 against the world number eight.
He is the third-youngest winner of a Masters 1,000 title after compatriot Rafael Nadal and the USA's Michael Chang.
Former world number one Juan Carlos Ferrero, Alcaraz's coach, had not been in Miami as his father had died before the tournament.
Alcaraz dedicated his semi-final win to Ferrero but the 42-year-old arrived unannounced in time for the final, for which he was courtside at the Hard Rock Stadium.
