On December 17, 2008, Torrington Twisters owners Robin Wadsworth and Rita Hubner, along with New Bedford mayor Scott W. Lang, announced the relocation of the franchise from Torrington, Connecticut to New Bedford, Massachusetts. Also made public was the fact that the team had entered into an agreement to lease the city's Paul Walsh Field for three seasons. At the press conference, Wadsworth was quoted as saying, "New Bedford has a sense of pride, community and passion that clearly shines through; their enthusiasm is second to none. It quickly became a virtual no-brainer, the minute we engaged with Mayor Lang, Matt Morrissey and other community leaders." The team, renamed the New Bedford Bay Sox, made its debut on June 4, 2009, in front of a home crowd of nearly 4,000 fans. On December 26, 2010, changes were announced in the Bay Sox ownership. While owners Wadsworth and Hubner maintained their positions, Tewksbury, Massachusetts residents Jim and Effie Dragon joined as minority partners in the operation. All owners voiced their interest in keeping the team in New Bedford. In October of 2011, Pat and Beth O'Connor - owners of the Little Fenway, Little Wrigley, and Little Field of DreamsWiffle ball parks in Essex, Vermont - purchased majority interest in the Bay Sox from Wadsworth and Hubner. The O'Connors would operate the team for the next five seasons. One of the O'Connors' first moves was to hire former MLB player Rick Miller as the Bay Sox manager in November of 2011. In his debut season at the helm, the former Boston Red Sox and California Angels outfielder would be named the NECBL's 2012 Manager of the Year. After three years as Bay Sox manager, Miller retired at the conclusion of the 2014 season. He was succeeded by his pitching coach, Westport, MA native and former Boston Red Sox draft pick Kyle Fernandes. Fernandes led the Bay Sox to back-to-back postseason appearances in his two seasons as manager. In December of 2016, local ownership took control of the Bay Sox when the O'Connors sold most of their shares in the team to Stephen King and Tammy Silveira. The pair would oversee operation of the ball club for its final three seasons, with Silveira serving as the club's general manager. Unfortunately, said campaigns saw the team finish last in the NECBL's Southern Division for three straight years. Exacerbating the team's woes in 2019 was the fact that nine of 21 Bay Sox home games were postponed by rain. At the conclusion of the season, it was announced that the Bay Sox were suspending operations and would not return to the NECBL in 2020.
