World number one Carlos Alcaraz downed America's last hope Taylor Fritz to reach back-to-back finals in the Miami Open.
The defending champion won 6-4 6-2 having managed to hold his "nerves" under the lights at Hard Rock Stadium.
He fired 20 winners in the match and conceded just 13 unforced errors to stay very much on course to retain his title in Miami in order to remain on top of the ATP world rankings.
"A little bit of nerves at the beginning of the match," Alcaraz said of facing Fritz.
"It was new for me, playing against him.
"I knew that I had to play my game, the way that I was playing the previous matches, at a high level for me.
"Of course, I'm very happy with the way I started the match, with no mistakes and with a lot of power.
"It was key for me to break his serve at the beginning and then [play] my game.
"I've played against him in the final rounds of tournaments.
"That means he is playing at a great level. Of course, I am sure that we are going to play for big things in the future.
"I can't wait to see our [improvement]."
The Spaniard will next face Jannik Sinner in the semi-finals of the Miami Open as he targets a 'Sunshine Double' after clinching the Indian Wells title earlier this month.
