Rory McIlroy will begin his title defence at the Amgen Irish Open alongside Ryder Cup teammate Robert MacIntyre and fellow Major champion Brooks Koepka.
The World Number Two, who is targeting a third national open title on the island of Ireland, is the headline act this week as the Back 9 continues with the DP World Tour making a first visit to Trump International Golf Links & Hotel, Ireland, Doonbeg.
Alongside MacIntyre and tournament invite Koepka, the star trio will tee off the first on Thursday at 13:35pm before beginning their second round off the same hole at 09:30 on Friday.
Ten minutes later, another home hero in Shane Lowry, a winner of this event as an amateur in 2009, is joined by two-time champion Jon Rahm and Patrick Reed, who leads the Race to Dubai Rankings Delivered by DP World.
With one of the strongest fields assembled in the tournament's recent history there are a number of eye-catching groups over the opening two day's scheduled play on the west coast of Ireland.
Sepp Straka, one of seven European Ryder Cup players from 2025 in action, is in a three-ball with Ireland's Seamus Power and Joaquin Niemann of Chile at 09:30am on day one.
In the immediate group after, Pádraig Harrington will start his 31st consecutive appearance at his national open, the longest uninterrupted streak since the event began in 1975, in the company of Tyrrell Hatton and Eugenio Chacarra, a two-time winner this season.
The tournament marks the third event in Team Europe's qualification process for next year's Ryder Cup at Adare Manor and Captain Luke Donald is grouped with Alex Fitzpatrick and Tom McKibbin as they begin their challenge at 13:15.
Rasmus Højgaard, champion at this event at Royal County Down in 2024, will start his week alongside Haotong Li and Thomas Detry at 2pm, while his twin brother Nicolai is also among the afternoon wave on Thursday alongside last week's winner Thriston Lawrence and Masters champion Sergio Garcia at 1:25pm.
