Fred Ridley, chairman of the USGA's championship committee, said that the change was made to add flexibility in the event of inclement weather.
'The two-tee start at the Open will result in nearly two hours more of daylight after the last starting time on each of the first two days, allowing more flexibility if inclement weather arrives,' said Ridley.
The USGA adopted the two-tee start for the U.S. Women's Open in 2000 and at the U.S. Senior Open this year.
The change now means that only the Masters and British Open are the only majors that do not use alternating tees. The PGA Championship went to this format this year.
