Paris Olympics: Ireland beat South Africa in opening rugby sevens clash

The Paris Olympics began in earnest on Wednesday when the first batch of pool games in rugby sevens kicked off in front of a noisy crowd at the iconic Stade de France where Ireland beat South Africa 10-5 in a blockbuster clash.

James Topping's side were the first of Team Ireland in action at these games and certainly delivered with a possession-dominant performance in Saint Denis, as Jordan Conroy and Terry Kennedy went over for tries in either half.

The opening game win puts Ireland in a strong position in Pool A heading into their second outing against Japan later this evening at 8pm Irish time. The Japanese side suffered defeat to New Zealand in the other Pool A clash this afternoon.

Although the Olympics opening ceremony is not until Friday, soccer and rugby sevens preliminary rounds got underway for logistical reasons in Paris and around the country.

The shorter but speedier rugby format allows teams to play more than one match a day and the medals in the men's and women's tournaments will be decided before the 81,000-capacity stadium hosts the athletics events from August 1st.

Scores of fans lined up outside the sun-kissed arena for the rugby sevens, the majority in blue to support the host nation.

"It's been excitement, emotions, impatience ... I've been looking forward to the start," said 44-year-old France fan Matthieu.

"We're at the heart of the biggest event that we've been waiting a long time to see."

Another France fan, Pauline from Toulouse, arrived with three kids in tow and there was no question who they were most keen to watch when they screamed, "Antoine Dupont!".

The 27-year-old is a former world player of the year in the fifteen-man format and made the switch to Sevens after last year's Rugby World
