MLS rivalry cups
In Major League Soccer, several teams annually compete for secondary rivalry cups that are usually contested by only two teams, with the only exceptions being the Cascadia Cup and the new Copa Tejas, which are contested by three MLS teams, each. Each cup or trophy is awarded to the eligible team with the better regular season record and are comparable to minor trophies played for in college football rivalries. Most cups are deliberately conceived as local derbies between teams in the same region. Rivalry cups are considered a tradition to most MLS fans and players alike. Out of the ten original MLS teams only three have not competed in these rivalry cups: Sporting Kansas City, New England Revolution, and the defunct Tampa Bay Mutiny. The Texas Derby is the only MLS rivalry where the winner does not walk away with a cup trophy but instead they play for "El Capitán", a replica 18th century mountain howitzer cannon. Some derbies only contest for bragging rights of rival supporters groups.
