"Located just minutes north of downtown Billings and framed against the picturesque Rimrocks, Cobb Field has been the home of the Billings Mustangs since the club's inaugural season of 1948. Originally known as Athletic Park, the 4,200 seat stadium was renamed Cobb Field prior to the start of the 1948 season in honor of Bob Cobb, the man responsible for bringing organized professional baseball to Billings."
