Carlos Alcaraz conjured up what initially appeared — to the chair umpire, to everyone watching in the stands or on TV and to his opponent, Ben Shelton — a remarkable lunging volley to win a point at the French Open on Sunday.

Following his French Open victory, Carlos Alcaraz expressed his admiration for Ben Shelton, calling him an "unbelievable player."

Frances Tiafoe joined his fellow American in the last-eight with a straight-sets victory over Daniel Altmaier. The 15th seed had never previously made it beyond the third round at Roland Garros, but he will face Lorenzo Musetti or Holger Rune for a place in the semi-finals.
