My men's team just started the 2013 spring season and we are short of players. Two weeks ago a player called wanting to join the team and I gave him the team number to sign up which he did. We have a match next Saturday and when I printed the match score card from Tennis Link I noticed that my opposing team had a player with the same name as one of my players. Drilling down deeper on Tennis Link, I realized that both teams have the same player on our roster(s). My League Coordinator says that is impossible but facts are facts. I talked to the player and he confirmed he joined two teams but says he "quit" the other teams after playing the first match. Could the computer have made an error?
