Open Division is a Blizzard run league, open to all players who placed in Masters or higher in the most recent season of ranked Competitive Play.
The league runs in several regions around the world, and is run through Blizzard Entertainment, ESL, FACEIT and Starladder.
Path to Pro
Beginning in 2018, Open Division became integrated into Contenders in the Path to Pro. The top 4 teams from a season of Open Division would now get to play the bottom 4 teams from the previous season of Contenders, in a relegation tournament named Trials. The top four in Trials would go on to play in the following Contenders season.
