Carlos Alcaraz won his first title on grass and regained the world number one ranking with an impressive victory over Alex de Minaur in the Queen's final.

The Spaniard, 20, who was playing only his third grass-court tournament, has won five titles this season.

He will now set his sights on a Queen's-Wimbledon double.

De Minaur, 24, was seeking to become the first Australian winner at Queen's since Lleyton Hewitt secured his fourth title in 2006.

The world number 18, who beat Andy Murray in the first round, tested Alcaraz throughout with his pace and agility around the court.

He had the first break point at 4-3 but the top seed shut that chance down instantly with a 137mph ace.

A De Minaur forehand error gave Alcaraz his own break-point opportunity in the next game and the Spaniard roared with delight when the Australian sent another forehand long.

Alcaraz demonstrated his ability on grass with a well-judged drop shot, a deft volley at the net, a thumping forehand winner and a huge ace as he wrapped up the first set in style.

The Spaniard, who made the fourth round at Wimbledon last year before losing to Jannik Sinner, called for the physio at the end of the set to receive help with a right quad issue.

With Alcaraz fit to continue, the pair went toe to toe in the second set, and the Spaniard acknowledged De Minaur's tenacity with a handshake at the net after the Australian came out on top of one mesmerising rally.

But De Minaur's standards slipped in the next game and a double fault handed Alcaraz the crucial break.

From there, Alcaraz's victory was inevitable and he clinched the title with his first championship point when De Minaur sent a return of serve out of play.
