Although much of the 163,000-squre-foot facility in Tavares won't be done until later this year, a volleyball tournament this month drew 5,000 people and 60 teams, the Orlando (Fla.) Sentinel reported Wednesday.
"We want to be a sports mecca," said Lemon. "We want people to be able to come here and play all these sports and have everything here."
Lemon -- a three-time all-star who played on the 1984 World Series champion Detroit Tigers -- said he and his wife, Gigi, began planning what they call "The Big House" 15 years ago.
At completion, it will have a major-league sized baseball outfield with extra batting cages and pitching mounds, a world-class fitness center, a running track and outdoor beach volleyball and soccer fields.
It also has a hair and nail salon, a car-detail shop, a smoothie bar and a food court.
Also in the works are a day-care center, classrooms, a 100-seat theater, a VIP lounges for visiting scouts and university recruiters, and an in-house webcasting center.
The Lemons' complex joins other large sports venues already in the Orlando area, including the Disney ESPN Wide World of Sports Complex.
