 Legal issues and financial obligations became overwhelming and coupled with the decline of the Sonoma County Crushers, another of the WBL flagship organizations, the Western Baseball League was dealt a critical blow, and folded shortly after the 2002 season.The Solano Thunderbirds, a college league team succeeded the Steelheads as Travis Credit Union Park's primary tenant but has never shared in the excitement or crowds enjoyed by Portner's Steelheads drawing fewer than 100 people to most of its games.Due to the poor management of the Solano Thunderbirds owned by Curtis, Susan and Byrant Stocking, they ran up debt in the millions of dollars and were forced to close down the Thunderbirds leaving Vacaville with no baseball team.
