Extreme Baseball, also known as Double Diamond Baseball, is a sport based on traditional baseball. The main difference is that both teams are on the field at the same time. Pitchers from each team take turns pitching to batters at two adjacent home plates. One team runs around the bases in the normal clockwise direction, while the other team runs around bases in a counterclockwise direction. The world premier game took place on May 5, 2007 at Historic Sanford Memorial Stadium in Sanford, Florida.

Extreme Baseball was conceived and developed by Phillip Weidner, an avid fan of traditional baseball. In 2006, Weidner applied for a United States patent on the extreme baseball concept and the concept and patent was pending as of 2007. Extreme Baseball teams from Saint Petersburg, Florida; Orlando, Florida; and Miami, Florida were competing as of 2007.
