LONDON — Iga Swiatek reached the Wimbledon semifinals for the first time with a 6-2, 7-5 victory over 19th-seeded Liudmila Samsonova that went from a stroll to a bit of a struggle in the late stages Wednesday.

Two power hitters competing in a slugfest early transitioned into a calculated display of consistency from World No. 1 Jannik Sinner during Wednesday's straight sets win over Ben Shelton in the quarterfinals at Wimbledon.

Organizers of this year’s Wimbledon have said a ball boy caused the latest error from the electronic system that has replaced the traditional line umpires at this year’s tournament.

World No. 1 Sabalenka had to grind out a tough win over No. 104 Laura Siegemund. Fritz cruised to his victory, setting up a semifinal against Carlos Alcaraz.

Defending champion Carlos Alcaraz faces Britain's Cameron Norrie in the Wimbledon quarter-finals on Tuesday, while world number one Aryna Sabalenka can move a step closer to her maiden All England Club crown.

Carlos Alcaraz’s next opponent Taylor Fritz has issued a warning to the Wimbledon champion ahead of their semi-final clash at the All England Club. Alcaraz is just two wins away from a third successive Wimbledon title after he thumped Great Britain’s Cameron Norrie in straight sets.
