Rory McIlroy has been grouped with World Number One Brooks Koepka and Australia's Jason Day for the opening two rounds of the WGC-FedEx St. Jude Invitational.
The trio have all topped the Official World Golf Rankings during their careers and will start their opening round at 12.59pm from the first tee.
McIlroy goes into the event on the back of missing the cut at the Open Championship at Royal Portrush despite a stunning second round display. On three of the last four occasions the four time Major Champion has missed a cut, he has gone on to finish in the top two of his next event.
Tommy Fleetwood finished runner-up at the Open and he will start his bid to win a first event on American soil when he tees off from the tenth at 11.31am. He will be joined by Australia's Marc Leishman and Patrick Cantlay from the United States.
The Open was a spectacle for sport. Proud to be a part of it. Many Congratulations to @ShaneLowryGolf , his family and his team on achieving a dream. Hopefully one day it can be me. Thank you everyone for your support always💪🏻#TheOpen @TheOpen pic.twitter.com/fix2ZvvluE
