Portland Mavericks
The Portland Mavericks. This renegade ball club existed for only five summers, but managed to leave an indelible stamp (their contemporary detractors might have said “stain”) on the landscape of minor league baseball. The Mavs came to town in 1973 after the Beavers, Portland’s long-time entry in the Pacific Coast League, moved to Spokane, Washington. It didn’t seem like a promising trade-off for Portland baseball fans …at least, not at first.
