Despite struggling at times in the first set, Alcaraz beat Alex De Minaur 6-4, 6-4 for his fifth title of the year and 11th overall.

That saw the 20-year-old Spaniard move above Novak Djokovic in the rankings and confirmed the U.S. Open champion as a serious challenger to the Serbian's crown at Wimbledon. Alcaraz lost in the fourth round to Jannik Sinner last year.

Sunday's final was Alcaraz's first on grass, in only the third tournament of his young career on the surface.

He had to save two break points in the eighth game of the first set, broke in the next game and then served out for the set.

Alcaraz won the only break point of the second set, when De Minaur double-faulted, and sealed the title on his first match point when the Australian sent a return long.
