The Omaha Storm Chasers attracted more than 466,000 fans during their second season at Werner Park.
The team says attendance was helped by the team's success on the field because four playoff games were also held at the 6,434-seat stadium. Average attendance for games was 5,938 in 2012.
The total attendance in 2012 was the highest since 1997 and the sixth-highest in franchise history.
