​The Los Angeles Valiant and San Francisco Shock announced the formation of the Overwatch California Cup, an esports event to determine the defender of the California Cup. 

​​The partnership will pit the two ​Overwatch League teams against each other to fight over California. The offseason showcase event begins Oct. 20 at the Esports Arena Santa Ana and finalizes Nov. 10 at the Esports Arena Oakland. 

 "Both locations will feature an intimate meet-and-greet with the new-look Shock and Valiant rosters, amateur and collegiate Overwatch tournaments, exclusive merchandise, free-to-play computers and more," the post read. "Each event will culminate in a match between the Valiant and Shock to determine the guardian of the California Cup." 

After the offseason showcase finishes, the Overwatch California Cup will pick up again during the Overwatch League Season 2 in January. The winner of the cup will take control of the California Cup until the next meeting.
