To roll out the 2010 season the San Diego Derby Dolls are hosting Arizona Roller Derby on Saturday, Jan. 23 at the Del Mar Fairgrounds for a flat track roller derby bout. The last time these leagues faced each other was in Arizona early in the 2009 season where SDDD’s Wildfires took a landslide win from AZRD’s Tent City Terrors with a score of 185-62. This time both leagues are fielding a “mixed team” – a team that rosters both A team players and B team players.
