Novak Djokovic recorded his 800th career win as he beat France's Adrian Mannarino 7-5 6-1 to reach the semi-finals of the Fever-Tree Championships.
Djokovic, 31, trailed Mannarino in the first set but the former world number one from Serbia went on to dominate.
The three-time Wimbledon champion will next face France's Jeremy Chardy, who beat American Frances Tiafoe 6-4 6-4.
Top seed Marin Cilic of Croatia and Australian Nick Kyrgios will meet in the other semi-final on Saturday.
Djokovic delight at career milestone
Djokovic is through to only his second semi-final of a troubled campaign as he seeks to secure his first title in 2018.
The 12-time Grand Slam champion is ranked 22 in the world after losing to Italy's Marco Cecchinato in the French Open quarter-finals.
Hampered by an elbow injury last year, Djokovic has failed to reach the semi-finals in any of his last five Grand Slam appearances and accepted a wildcard to Queen's as he seeks to regain his best form before Wimbledon starts on 2 July.
If Djokovic wins the semi-final and goes on to take the Queen's title for the first time, he will pass Stefan Edberg in ninth place on the all-time list for most men's singles wins.
Jimmy Connors heads the list with 1,256 wins ahead of second-placed Roger Federer, who has 1,156.
"It's a milestone, and of course it's a great achievement," said Djokovic about his 800th victory. "Every achievement is a great achievement. I should be happy for it and proud of it.
"When you work all your life for something and then you get rewards for it, of course it's obviously very positive and I'm thrilled.
"I'm grateful, as well, as I'm able to play so many matches and to win so many matches in my career.
"It's still the sport that I love with all my heart. I put in that heart every single day, and I'm very glad to be able to play semi-finals here after Rome and Roland Garros tournaments that went pretty well for me."
Kyrgios serve too good for Lopez
Kyrgios hit 32 aces as he continued his impressive run by knocking out Spain's 2017 champion Feliciano Lopez 7-6 (7-5) 7-6 (7-3).
The 23-year-old also hit 32 aces in his second-round victory over Kyle Edmund and 18 against Andy Murray in the first round.
"I can't remember a specific time where I've served at this level back to back," said the Australian world number 21.
Cilic, who reached last year's Wimbledon final and was runner-up at this year's Australian Open, beat American Sam Querrey 7-6 (7-3) 6-2.
The 29-year-old hit 10 aces and won 91% of first-serve points to reach the semi-finals for the third year in a row.
