Day in standout grouping at The Open
Jason Day will play with Masters champions Danny Willett and Rickie Fowler in the opening two rounds at the 145th Open at Royal Troon.
World number one Day is part of match 16, and will be followed by 2014 champion Rory McIlroy, Hideki Matsuyama and Bubba Watson.
Jordan Spieth, meanwhile, plays with Justin Rose and Shane Lowry, while US Open winner Dustin Johnson is alongside Martin Kaymer and Russell Knox.
Colin Montgomerie has been invited to hit the opening tee shot at his home course, where his father was club secretary for over 20 years.
"It is a great honour. I hit my first shot of golf when I was six years old on the children's course, which is now the TV compound, I believe," he said.
"This is where I started playing and this is home. There's not many pros here that have the opportunity to play an Open on their own course where they're members of."
