The Boulder Collegians were formed by the late, great Bauldie Moschetti in 1964, and quickly became one of the top collegiate summer baseball programs in America. From 1965-1980, the Collegians competed in the National Baseball Congress national championship tournament every season, winning four national championships, finishing runner up once and collecting eight other top five finishes.

During those glory years, the Collegians competed in the famous “Midnight Sun” game in Fairbanks, Alaska in 1969, and featured a who’s-who of future Major League Baseball standouts. Hall of Famer Tony Gwynn, World Series hero Joe Carter, National League Rookie of the Year Bob Horner and World Series managers Joe Maddon and Terry Francona were just five of more than 100 former Collegians to reach the big leagues.

Moschetti retired the Collegians in 1980, following a 64-12 season that concluded with a third place finish at the NBC in Wichita, Kansas.

In 2013 Matt Jensen brought the Collegians out of mothballs and guided them for several years. Following the 2020 season, Jensen passed the torch to Tony Rouco, who led the team to consecutive MHCBL championships in 2021, 2022, 2023 and 2024.
