McCoy Stadium is a former baseball stadium in Pawtucket, Rhode Island. From 1970 through 2020, it served as home field of the Pawtucket Red Sox (PawSox), a Minor League Baseball affiliate of the Boston Red Sox. Completed in 1942, the stadium first hosted an affiliated minor league team in 1946, the Pawtucket Slaters, a Boston Braves farm team. In 1981, the stadium hosted the longest professional baseball game in history, as the PawSox defeated the Rochester Red Wings in 33 innings by a score of 3–2. History Early years The project to build the stadium began in 1938 and was championed by then-Pawtucket Mayor Thomas P. McCoy. It was to be built on a swampy piece of land known as Hammond's Pond and, to this day, the stadium sits at the end of Pond Street. On the afternoon of November 3, 1940, Mayor McCoy laid the foundation cornerstone. Initially known as Pawtucket Stadium, it was completed in 1942, and in 1946 was officially named in honor of Mayor McCoy, who had died in August 1945. McCoy Stadium first began hosting affiliated Minor League Baseball in 1946. The Pawtucket Slaters, a Class B affiliate of the Boston Braves, was the first team to call McCoy Stadium home. The Pawtucket Slaters would play for four seasons in the New England League, as Braves affiliates. Professional baseball disappeared from Pawtucket for 16 years. It finally returned in 1966, as McCoy became home of the Pawtucket Indians, who competed at the Double-A level in the Eastern League as an affiliate of the Cleveland Indians. After two seasons, the Indians moved to Waterbury, Connecticut, and McCoy was again without a team. Red Sox arrival In 1969, the Boston Red Sox had their Eastern League affiliate, the Pittsfield Red Sox of Pittsfield, Massachusetts, play at McCoy Stadium twice—one game in July and a doubleheader in August; the two events drew a total of over 10,000 fans. After the season, it was reported that the Pittsfield Red Sox would be relocated to McCoy Stadium. The team moved prior to the 1970 season, becoming the Pawtucket Red Sox, known colloquially as the "PawSox". The franchise spent three seasons playing in the Double-A Eastern League before being promoted to the Triple-A International League. In 1976, debt-ridden owner Phil Anez threatened to move the team to New Jersey, but sold the franchise to Marvin Adelson, who lost the ballclub after
