2009 Shinhan Bank Winners League
The Winners League format is a Best of Seven between teams where each team would send out one player on the first map and whichever player won would stay to play until they lost a game. Each team played each other in a Round Robin format. After all teams have played each other, the top six teams were put into a bracket based on final rankings.
The 2009 Shinhan Bank Winners League was the first time a round of Proleague used the Winners League format. Winners League was the third round of the 2008-2009 Shinhan Bank Proleague.
