The three-day Big O Tournament takes place May 5-7 at the Lane Events Center, and will host 35 women’s, men’s, and junior roller derby teams. Teams from as far away as Argentina, Sweden, and Finland will be competing this year, as well as many of the highest-ranking teams in the world. Competition is fierce and the stakes are high. Teams compete to gain ranking points to attend playoffs, and to ultimately compete for the title of world champion. Teams include the repeat 2015 & 2016 Women’s Flat Track Derby Association (WFTDA) World Champions, Portland's Rose City Rollers, along with six more of the top 10 women's teams including Victorian Roller Derby League, Angel City (Los Angeles), Arch Rival Roller Derby, Denver Roller Derby, and the Texas Rollergirls. Local Lane County Concussion and Emerald City Reservoir Dolls will be playing in the men’s and junior divisions, respectively. The 2016 Men's Roller Derby Association (MRDA) World Champions-the St. Louis Gatekeepers-will also be competing, along with several other top-ranked men's teams including Portland's Bridgetown Menace and Puget Sound Outcast Roller Derby. The full line-up of teams is available on our website at http://ecrg.com/bigo/2017teams/.
