NEW YORK — Rays principal owner Stuart Sternberg wouldn't reveal any of the details about the Ybor City stadium that will be announced Tuesday but said he's confident the plan will be well-received."People are going to love the place," Sternberg said Friday. "They're going to love it."The Rays have called a Tuesday news conference to "unveil their plans" for what they are calling a "next-generation, neighborhood ballpark," at which they are expected to unveil renderings of the design — including whether it has a retractable roof and natural grass — and details about the cost. With estimates of at least $800 million, working out the financing, including how much the team will pay, is considered the most significant hurdle in completing the project.As for the overall plan, Sternberg said: "I couldn't be happier about it.""We've been marching toward this day and event for years," he added. "To be at the point where we are now, after the announcement of the site earlier this year, shows all the work and effort and determination that we've had. … I know the effort and the love to get to this point, and I fully expect people are going to love the outcome."
