World number one Carlos Alcaraz kicked off his title defence at the Miami Open with a resounding victory.
The Spaniard beat Argentine Facundo Bagnis 6-0 6-2 to extend his head-to-head record against the clay-court specialist to 4-0.
It only took the 19-year-old US Open champion 65 minutes as he bagelled Bagnis in the first set before easing his way through the second to seal victory.
"I knew that I needed to be focused for my first match," said Alcaraz who won the Indian Wells title last week.
"To start a new tournament is never easy.
"I have to be ready to get used to these new conditions, but I was really focused on the match from the beginning and I'm happy with the way that I played."
Alcaraz will next meet Dusan Lajovic or No. 30 seed Maxime Cressy in the third round as he bids to retain his Miami title.
