Prior to the 1969 season, MLB expanded by an additional four teams, raising the amount of teams from just eight to twelve. It took a long time for the MLB to expand, but once it started, they sure kept the ball rolling. In just 30 years, they’d expanded to 30 teams. One of those teams, the San Diego Padres, has a rich trading history with the Cardinals. In fact, the Cardinals first trade with the Padres predates the 1969 season. I thought I’d try something new today, and look over the Cardinals history one with specific franchise.
