Darren Clarke and Rory McIlroy have received awards for their 2011 success in the New Year Honours list.
Open winner Clarke becomes an OBE while fellow Northern Irishman McIlroy is appointed an MBE for his US Open win.
Clarke, 42, fired a final-round 70 at Royal St George's in July to finish five under par and hold off Americans Phil Mickelson and Dustin Johnson.
"It is a great honour and a fantastic way to end a great year. I am very proud for me and my family," said Clarke.
McIlroy, 22, won the US Open in Washington in June and climbed to number three in the world rankings.
He became the youngest US Open champion since Bobby Jones in 1923, who was just 21, and the youngest major winner since Tiger Woods triumphed at the Masters in 1997 while 21.
McIlroy was "humbled" to be on the list and said: "Many people on the honours list have made huge personal sacrifices and contributed significantly to society during their lives. I feel very fortunate to be in their company."
Clarke and McIlroy were both nominated for the BBC Sports Personality of the Year award, with Clarke coming second to cyclist Mark Cavendish.
