Hickey said he has sold Mansfield SportsPlex, a 70,000-square-foot recreation and fitness facility and restaurant on Oxford Road in Mansfield, near the Foxboro town line. He owned the business for 20 months, buying out partner Robert Adair of Foxboro after three months. Hickey said the sluggish economy was not a factor in his decision to sell the sportsplex. "The business itself is going great," Hickey said. "It was time to sell it and do something where I'd have a little more time for my family and civic obligations." He said that on April 28 he will return to State Street Corp. as an officer. A former account manager with State Street, he had been with that company for 61/2 years prior to going into his business for himself. Previously stationed in North Quincy, he will now work in the company's Boston office. "It was fun, it was good, but at the same time it's good to be done," he said of the business. "The business is strong, but with a new owner with better financial backing, I anticipate the business will thrive even more. Youth sports is very strong in this area." He declined to name the buyer, saying his lawyer has yet to complete the sale arrangements. He said the buyer was not a Foxboro resident or a fitness chain. In August 2006, Hickey and Adair purchased the former Dana Barros Sports Complex for more than $3 million, Hickey said at the time. The former Boston Celtics star had walked away from the enterprise. Built in 1974, the building had been a tennis club and later a trucking warehouse before it was converted into a sports center.
