Trinh Linh Giang played first, facing Mainguy Clement. Giang let Clement win the first set, but came back stronger in the next two sets to claim victory.
In the second match, the key player of Vietnam, Ly Hoang Nam, battled Colin Sinclair, the star of Pacific Oceania. Sinclair won the first set and Nam equalized, but the Vietnamese lost in the last set.
After two matches, the score was 1-1 and the result was decided by the final match, as Nam and Le Quoc Khanh played Sinclair and Baudinett Brett in the doubles. The Vietnamese players won the first set, before Pacific Oceania equalized. In an intense third set, Nam and Khanh wrapped it up with a triumph. Overall, Vietnam won 2-1 after 7.5 hours of competition with Pacific Oceania.
This victory pushed Vietnam to the top of their group. The team will play Qatar on the second day Thursday.
Previously, Vietnam had been chosen to host group three of the Davis Cup Asia-Oceania zone. But because of the ongoing Covid-19 wave in the country, the International Tennis Federation instead appointed Jordan as host.
