Alcaraz beats Korda to reach Queen's final, De Minaur awaits after defeating Rune
Alcaraz lost his opening set at Queen's earlier in the week but has since looked ominously good and proved too powerful for Korda, winning 6-3, 6-4.
In his first ATP Tour final on grass, Alcaraz will face Australian Alex de Minaur who earlier beat Danish second seed Holger Rune 6-3 7-6(2).
Should Alcaraz win Sunday's final he would reclaim the world number one ranking from Novak Djokovic and would be seeded one at Wimbledon which begins on July 3.
Korda was at full stretch to try and keep Alcaraz at bay in the opening set but still dropped serve twice, although he did also manage to break the Spaniard.
Alcaraz began to unleash some heavy groundstrokes and showed plenty of grasscourt acumen despite being a relative novice on the surface. He forged an early break ahead in the second set and never looked in danger from that point on.
"Every match I feel better and I feel like I've been playing on grass for 10 years," Alcaraz, who will attempt to emulate Rafa Nadal by winning Wimbledon next month, said on court.
"I'm playing great and feeling great. Very happy to make my first final on grass and even more so at Queen's."
Fellow 20-year-old Rune had not dropped a set on the way to the semi-finals but found the livewire De Minaur a step too far as he fell short of also reaching his first final on grass.
World number 18 De Minaur, who put out home favourite Andy Murray earlier in the week, is aiming for his second career title on grass having won at Eastbourne in 2021.
He is the first Australian to reach the final at the Queen's pre-Wimbledon event since Lleyton Hewitt in 2006.
Two breaks of serve allowed the seventh seed to cruise through the first set but he was pushed much harder in the second with both players forced to save break points.
However, De Minaur's greater experience on the slick lawns showed as he polished off the tiebreak.
"I play pretty decent on the grass, I love playing on this court," he said.
"Today was my best match so far this week. I just hope that I can go one better tomorrow."
