Italy's Lorenzo Musetti knocked defending champion Alexander Zverev out of the Olympic Games tennis tournament on Thursday.

Musetti triumphed 7-5, 7-5 over the German world number four in the quarter-finals and will face either top seed Novak Djokovic or Stefanos Tsitsipas for a place in the gold medal match.

Earlier, World No. 3 Carlos Alcaraz of Spain stormed into the semi-finals with an imperious display of tennis.

Alcaraz, playing on the same Court Philippe Chatrier at Roland Garros where he captured the French Open in June, saw off 13th-ranked Tommy Paul of the United States 6-3, 7-6 (9/7).

The 21-year-old Alcaraz recovered from a break down in the second set to defeat Paul, having also beaten the American in the quarter-finals at Wimbledon on his way to the title at the All England Club last month. (AFP)
