Often leagues will end up with an odd number of players or teams. How do you set that up? Golf League Tracker requires that an even number of players be set (if an individual player league) or an even number of teams if a team league.
When setting up the player count in your league settings, the system will give you an error if you enter an odd number. To fix this, increase the player count by 1, and enter a "ghost" player in your player list to take this final spot.
To accomplish this you need to create two ghost players, and assign them to a single team.
Ghost players are simply a player in your player list who isn't real. You can name them whatever you like. "Ghost Player" is often chosen, but some leagues choose to use real names (e.g. "Tiger Woods"). Just make sure it's obvious to your players that their opponent isn't real!
Most leagues treat a ghost player or team just like a real team who is absent for the week. Take a look at this help article on how to enter scores for absent players or teams here.
Should I Give a Player/Team a Bye Week Instead?
A "bye" means that the player or team doesn't play at all and they get 0 points. This situation only works if everybody has the same number of bye weeks. For example, if you have 15 real players (meaning #16 is the "ghost"), you would have to play either 15 or 30 rounds in order for each player/team to get the same number of byes.
Frankly, an odd number of players or teams stinks. In an individual player league you'll have some groups playing as a threesome, while in 2-player team leagues it means a team will be on their own playing as a two-some. A better solution is to call your course before your league starts and see if they have a list of people who are wanting to join a golf league! I've done this many times to fill in spots and it works great. I haven't had an odd number of teams on my league since I started doing this, we always fill the remaining spot.
