Hong Kong, China badminton star Lee Cheuk-yiu made a winning start in his maiden Olympic appearance, beating Mexico's Luis Ramon Garrido in the group stage of the men's singles tournament.

Lee, the world number 17 who missed out on a spot for the Tokyo Games in 2021, overpowered his opponent 21-5 in the first game.

But 66th-ranked Garrido, who was also making his Olympic debut in Paris, took the ensuing game 21-15 to force a decider.

The pair exchanged leads in a nail-biting finale, but Lee eventually came out on top after pulling away late on to win 21-17.

The top men's shuttler from the SAR next faces Chou Tien-chien of Chinese Taipei Wednesday evening, Hong Kong time. The winner of that match will advance to the round of 16, as Chou had already beaten Garrido earlier in their group tie.

It's a different story for another local badminton player, Happy Lo, who ended her Olympic journey after losing her second straight group match.

Supanida Katethong of Thailand beat Lo 21-14, 21-9.
