Pickleball is helping to revive vacant malls in the United States, according to research by Jones Lang LaSalle (JLL). Pickleball America has leased over 80,000 sq. ft. in a former Saks Off 5th in Stamford Town Center, Conn., a 32-court indoor pickleball facility will be part of a larger redevelopment of the Macon Mall, in Macon, Ga., and the All-Stars Pickleball Club converted a 25,000-sq.-ft. former Old Navy store at Steeplegate Mall in New Hampshire.
