Rory McIlroy, fresh off a devastating U.S. Open loss, was listed in the initial field released Monday for this week's PGA Tour event in Cromwell, Connecticut.
The Northern Irishman was in position to end a decade-long hunt for his fifth major Sunday but had three bogeys in his final four holes -- including two where he missed putts inside of 4 feet -- and lost to Bryson DeChambeau by 1 stroke.
The moment DeChambeau's winning putt dropped in the cup, McIlroy walked into the locker room to gather his belongings and then right to his courtesy car, leaving the site within minutes without answering questions.
It was his fourth runner-up finish in a major.
"At the end of the day we are all human," said Matthieu Pavon, who finished fifth. "Rory has been chasing another major many years. He is one of the best players in the world, a true champion. It shows you how tough it is."
McIlroy is scheduled to hold a pre-tournament news conference Wednesday following his pro-am at the Travelers Championship at TPC River Highlands.
The Travelers Championship is the eighth and final signature event of the PGA Tour season and does not have a cut, meaning the full 72-player field will compete all four rounds.
