There is a good schedule for 9 golfers playing 4 rounds in 3 threesomes, for example see http://www.maa.org/editorial/mathgames/mathgames_08_14_07.html. It looks to me like a good solution for you would be to add player 10 to one of the threesomes on each day. Players 1 through 9 will see each other exactly once. Player 10 will see a couple of others several times, and maybe some players (I think maybe two) zero times. Offhand I don't know if it is possible to do better. Have fun.
