ALBUQUERQUE N.M. – The Albuquerque Isotopes have once again led the Pacific Coast League in attendance, drawing 493,849 fans to Rio Grande Credit Union Field at Isotopes Park during the 2025 season. That total ranks fifth among 120 Minor League Baseball teams nationwide.
This marks the fourth consecutive year the Isotopes have paced the league in both total and average attendance. The team averaged 6,765 fans per game, placing eighth overall in MiLB. Six games drew crowds of over 10,000, including a season-high of 12,184 fans on July 4th—the fourth-largest single-game attendance in Minor League Baseball this year.
The club also reached a milestone this week, welcoming its 12 millionth fan since its inaugural season in 2003. Over 22 seasons, the Isotopes have drawn a cumulative 12,014,216 fans.
The Isotopes were founded in 2003, when the Calgary Cannons relocated from Alberta to Albuquerque. The move followed a $25 million renovation of the old Albuquerque Sports Stadium, resulting in the creation of Isotopes Park, where the team has played ever since.
The team’s name was inspired by the fictional “Springfield Isotopes” from The Simpsons, and was chosen through a public vote. The connection to nuclear science also resonated locally, given New Mexico’s ties to Los Alamos and Sandia National Laboratories.
The Isotopes have been affiliated with three Major League clubs: the Florida Marlins (2003–2008), Los Angeles Dodgers (2009–2014), and currently the Colorado Rockies (2015–present). They’ve won three division titles—in 2003, 2009, and 2012—but have yet to claim a league championship.
Before the Isotopes, Albuquerque was home to the Albuquerque Dukes, a storied franchise affiliated with the Dodgers that won multiple Pacific Coast League titles in the 1970s and 1980s.
