The 2023 Horizon Irish Open format remains unchanged this year, with the DP World Tour event played at The K Club, Straffan, Co. Kildare, Ireland.
The 2023 Horizon Irish Open field is 156 players.
The Horizon Irish Open field is made up of many top players as well as a variety of DP World Tour players competing in a tournament that is one of the longest-running events on the schedule. Rory McIlroy, Shane Lowry, Adam Scott and Adrian Meronk headline the field.
Horizon Irish Open format
The Horizon Irish Open format is a 72-hole event. The field is divided into morning and afternoon waves for the first two rounds, with players competing in threesomes each day. The same threesomes play together in each of the first two rounds, with one round starting on No. 1 tee and one round on No. 10 tee. There's one round in the morning wave and one round in the afternoon wave.
A cut is made after 36 holes to the top 65 players and ties.
For the third and fourth rounds, pairings and tee times are made based on each player's total score through two and three rounds, respectively. Players with the highest total score go first, then in descending order until the two players with the lowest total score in the final group.
The player with the lowest total score after 72 holes is the winner.
A playoff to settle any ties after 72 holes will be played under DP World Tour rules. The Horizon Irish Open playoff format is a sudden-death format, with playoff holes being 18 and played by any qualifying players. The players compete hole-by-hole until a winner is determined by a player scoring the lowest among the remaining players.
The winning player will get a two-season DP World Tour exemption. The winner is exempt into other tournaments as well. The winner earns 1005 DP World Tour points.
