World number one Jannik Sinner shrugged off any doubts about his fitness to reach the Wimbledon semi-final for the second time with a clinical defeat of American Ben Shelton on Wednesday.
A high-octane contest on a muggy Court One was decided by slender margins with Italian Sinner seizing the few opportunities that came his way for a 7-6(2) 6-4 6-4 win.
On the women's side, Poland's Iga Swiatek walloped Liudmila Samsonova 6-2 7-5 to reach the tournament's semi-finals for the first time.
After years of nightmare outings at the spiritual home of lawn tennis, Swiatek appears to have finally conquered her grasscourt demons as she said the "ball has been really listening" to her at Wimbledon this year.
"Honestly, it feels great. I have goosebumps after this win. I am super happy and super proud of myself and I will keep going," the eighth seed told the crowd after setting up a semi-final showdown with unseeded Belinda Bencic.
Switzerland's Bencic won two tiebreaks to beat teenage Russian seventh seed Mirra Andreeva 7-6(3) 7-6(2) and become a first-time Wimbledon semi-finalist.
The only mother left in the singles draw had four match points after Andreeva double-faulted in the second tiebreak on Centre Court and needed only the one, sealing victory with a smash at the net.
