Mickelson, of course, is also a three-time Masters champion, so he has extra incentive to play well this week and build his confidence for a run at a fourth green jacket. Phil tees off for Thursday’s opening round at 1:15 p.m. ET (12:15 p.m. local time) alongside Viktor Hovland and Jason Day.
Other notable groupings for the first round include Brooks Koepka, Jordan Spieth and Lanto Griffin (8:25 a.m. ET); Dustin Johnson, Tyrrell Hatton and Adam Scott (1:05 p.m. ET); Shane Lowry, Ted Potter, Jr. and Henrik Stenson (8:15 a.m. ET); and Sergio Garcia, Tony Finau and Brian Gay (8:35 a.m. ET).
