Five-time Major champion Phil Mickelson is among the latest group of stars who have been confirmed to play at the JP McManus Pro-Am at Adare Manor in 2020.
Mickelson, who is making Pro-Am debut, last competed at a tournament in Ireland back at the 2006 Ryder Cup.
Hollywood stars Mark Wahlberg, Hugh Grant and Jamie Dornan are among the list of confirmed amateurs who will also be attending the event, which will take place from 6-7 July next year.
Mickelson is joined by Ryder Cup stars Sergio Garcia, Jon Rahm, Henrik Stenson and Paul Casey as part of an impressive line-up being assembled for the sixth staging of the event.
Rahm and Garcia are also making their first appearances at the tournament, while Casey and Stenson previously played in 2005 and 2010 respectively.
All five players featured at Le Golf National last year, with Rahm, Garcia, Casey and Stenson helping Team Europe to victory over Mickelson’s American side.
The group will join Tiger Woods, Rory McIlroy and Justin Rose in Limerick in 2020.
Speaking about the latest additions to the line-up, McManus said: "It’s fantastic to have more of the game’s top players joining what is an ever-increasing line-up at Adare Manor.
"I have been hugely impressed with the manor of their various victories in recent years and we are very grateful to them for lending their support to the Pro-Am next year. Hopefully the thousands of Pro-Am spectators will be delighted with this news."
