The last three U.S. Open champions will be grouped together during the first two rounds of the tournament, which begins June 15 at Erin Hills in Wisconsin.
Defending champion Dustin Johnson, Jordan Spieth and Martin Kaymer will tee off at 9:35 a.m. ET at the year's second major championship. Johnson won last year's tournament at Oakmont; Spieth edged Johnson a year prior at Chambers Bay; and Kaymer was the 2014 champion at Pinehurst.
Phil Mickelson, who said he plans to withdraw from the U.S. Open because of a conflict with his daughter's high school graduation ceremony, is listed in a group with Steve Stricker and Stewart Cink at 3:20 p.m. He would be replaced by an alternate from sectional qualifying.
