Trenton Thunder
Double-A affiliate turned MLB Draft League team in Trenton.
The Trenton Thunder are a collegiate summer baseball team that competes in the MLB Draft League and calls Trenton, New Jersey, home. Their home field is Trenton Thunder Ballpark. Before joining the Draft League in 2021 as an unaffiliated club, the Thunder spent 27 seasons as a Double-A affiliate in the Eastern League, partnering with the Detroit Tigers (1994), Boston Red Sox (1995–2002), and New York Yankees (2003–2020). The team’s shift came after Major League Baseball reorganized its minor league system following the 2020 season.
The franchise began in 1994 when the London Tigers moved from London, Ontario, to Trenton. That team had previously played in Glens Falls, New York, as the Glens Falls White Sox and Glens Falls Tigers. The Tigers affiliation carried over for just one year before the Thunder switched to the Red Sox. As a Red Sox affiliate, the club finished first in its division three times but lost in the first round of the playoffs each time. In 2003, the Thunder became the Yankees’ Double-A team, while the Portland Sea Dogs took over as Boston’s affiliate—a swap that matched the fan bases of central New Jersey (Yankees territory) and Maine (Red Sox territory).
In 2006, the Thunder became the first minor league team at the Double-A level or below to draw over 400,000 fans for 12 straight seasons. By that point, more than 5.4 million people had attended Thunder games. A single-game attendance record of 9,212 was set on July 3, 2011, when 9,212 fans showed up for a Derek Jeter rehab appearance. That mark surpassed the previous record of 9,134 set on May 23, 2007, when Roger Clemens made his second minor league rehab start. The Thunder won their first Eastern League championship on September 15, 2007, defeating the Akron Aeros, and repeated as champions on September 14, 2008, with a 5–1 win over the same team. They lost the 2010 championship series to the Altoona Curve.
In 2013, Minor League Baseball’s website named the Thunder the Minor League Team of the Year. The team also won “Promo of the Year” for a retirement party honoring team bat dog Chase That Golden Retriever, which included a bobblehead giveaway, and “Mascot of the Year” for an online video that received the most views of any mascot video.
On November 7, 2020, the Yankees ended their affiliation with the Thunder, choosing instead to partner with the Somerset Patriots.
