100,000 people are expected to watch the Rugby World Cup 7s which starts on Saturday and ends on Monday at the AT&T Park in San Francisco.
This is according to the World Rugby 7s twitter page.
They had earlier announced that 80,000 tickets had already been sold.
Meanwhile, AT&T Park has had some works done on it to prepare it for the tournament.
Ground staff at AT&T Park are working to turn the home of baseball's San Francisco Giants into a rugby field.
According to 1 News, it requires the removal of 200 tonnes of dirt and the re‑laying of 28,000 square feet of grass as well as adjustments to certain areas of the park.
Head groundsman Greg Elliot said his team was up for the challenge.
The re‑transfiguration started straight after the San Francisco Giants game on Sunday with the diamond being dug up.
Elliot admits his crew’s biggest enemy is the deadline.
He thinks the biggest obstacles right now are the time-lines adding the time constraints and all the other construction that needs to be done.
In its 18‑year existence, the 42,000 capacity stadium has hosted football and college sport but not rugby.
