WrestleMax STL’s top prize is the River City Championship. Mike Outlaw was the inaugural champ from last defeating JDX in a tournament final on April 3, 2021.
The one-night tournament at the second WrestleMax STL card was the second annual David Lee Memorial Tournament. Although Outlaw guaranteed his title recognition on this date, the company officially withheld his “champion” status until the belt presentation in Summer 2021.
