Pickleball is a growing hit across the country, with over 50 million Americans are playing the sport. The sport has gotten so big it's now taking over the Stamford Town Center.

The old Saks Off 5th in Stamford is now 42,000 square feet of 13 pickleball courts called Pickleball America.

"We just want people to experience it, feel that they are comfortable with the space, the ceilings, the columns, the flooring and just have fun." said Pickleball America owner Jay Waldner.

This is one of the largest indoor pickleball venues in America. It opened Monday.

It's starting a trend of converting former stores into many happy returns.

"There's a lot of factors outside that people don't want to deal with so then they want to come in here," said Waldner.

Thirty-minute lessons are free this week from 11 a.m. - 1 p.m. Picklers will tell you anyone can play.

"It is something that people see it as very social. So, now it’s a smaller court, and it brings everybody down to a level where you can actually play," said Waldner.

Fourteen more courts are coming upstairs.

Waldner says some of the best pickleball players in the country may be coming to play at Pickleball America this summer.

The official ribbon cutting is Sept. 14.
