Dallas Senior Interclub....

The Dallas Senior Interclub - DSI - is an interclub golf league consisting of 10 top level DFW area clubs. The list of participating country clubs for 2019 and the tournament schedule is shown below.
The DSI organizes competition between all participating clubs with tournaments conducted at each club and a season-finale tournament between the 4 best performing club teams. DSI events are conducted April through September, usually on Monday or Tuesday morning. The championship tournament is usually held in September.

All male Thorntree MGA members who are at least 50 years old and have a handicap of 24 or less are welcome to play in the DSI. If you're interested in playing please email us, we'll add you to list of available players. NOTE: You are not expected to play in all 10 events

About 10 days before each DSI event, everyone that expressed an interest in playing in the DSI league is contacted by email and asked if they're interested in playing in the upcoming event. The 10-person Thorntree team is selected from those that respond saying they want to play in that event.

Tournament Format
The modified stableford quota format makes for a very fair competition. Each club fields a 10-person team; and the best 8 scores based on each player's result versus their quota are used to determine the winners of each event. After each event, each participant's stableford quota is adjusted upward or downward based on their performance in that event.


  • There is a one-time $30 annual enrollment fee for each player to join the DSI (payable when you play in your first tournament).
  • Each tournament participant pays a $30 entry fee which funds the prize money for that event. All prize money ($3,000.00 per event) is paid out to the top five teams as shop credit at the host club's pro shop.
  • Each participant is charged a cart fee, typically $20-$25. No greens fees are charged.
  • Lunch is available (optional) after each event for $20-$25.
