(Pawtucket, RI) -- Pawtucket is commissioning an economic study of the two proposed sites for a new baseball stadium. One site is the existing 75-year-old McCoy Stadium the other is what's known as the "Tidewater Site" along the Seekonk River. Pawtucket's Director of Administration Tony Pires says the "Tidewater Site" near the downtown area "might be the most effective." The former Apex Department store is currently on that site.
