The list of players participating in this years open tryouts with the Wizards has now come out. The list has 181 players on it. Those players have been divided into 16 teams. Next Saturday the teams will compete in 7v7 games starting at 9am out at the Wizards training facility in Swope Park. Those players will then be cut down to 60 players who will be invited back for the second day. Those 60 players will play 11v11 starting at 9:30.
If you are one of the participants, you can see what other information you need by checking here. If I get some time, I'll try to see if I can find any of this year's participants through google.
