Over the course of its inaugural season, Overwatch League has shown solid growth throughout the 200+ games played since its debut. While Blizzard's esport experiment has seen its fair share of ups and downs--resulting in some unexpected roster shakeups, changes to the flow of the schedule, and some controversies surrounding players--the league's success with turning the hero shooter Overwatch into an event game has been a sight to behold. The tournament will culminate in a battle between fan-favorite teams the London Spitfire and Philadelphia Fusion. And with plans to expand further in the next season, including two new teams in Paris and Guangzhou, along with a substantial distribution deal with ESPN, the future looks bright for Overwatch League.

Spanning July 27-28, the Grand Finals will see the London Spitfire and Philadelphia Fusion compete in several games, with the champion crowned after a best two of three matches contest. While the first day will only have one match, the second day of the Grand Finals will decide the winner.
