Dustin Johnson, Jordan Spieth, Martin Kaymer
Thursday tee time: 8:35 a.m. (hole 10)
Johnson, Spieth, and Kaymer are the last three U.S. Open champions - at least one of them figures to be in contention come Sunday.
Jason Day, Rory McIlroy, Justin Rose
Thursday tee time: 2:09 p.m. (hole 1)
Day and McIlroy are not always as consistent as golf fans would like, but when they get it going, they are virtually unbeatable. Rose fell in a playoff to Sergio Garcia at the 2017 Masters back in April.
Hideki Matsuyama, Rickie Fowler, Jon Rahm
Thursday tee time: 7:51 a.m. (hole 1)
Matsuyama and Fowler might be the two best golfers who are yet to win a major. Plus, check out Fowler's sweet bag.
The Big Bombers
Bubba Watson, Adam Scott, Sergio Garcia
Thursday tee time: 1:36 p.m. (hole 1)
There are four green jackets between these three golfers - let's see if they can bring that success over to a U.S. Open track.
The International Dark Horses
Henrik Stenson, Charl Schwartzel, Louis Oosthuizen
Thursday tee time: 1:47 p.m. (hole 1)
All three golfers have one major championship on their resume. Can they add another at Erin Hills?
The Steady Hands
Matt Kuchar, Francesco Molinari, Patrick Reed
Thursday tee time: 8:24 a.m. (hole 10)
No matter what, Kuchar, Molinari, and Reed always seem to be hanging around on major weekends. Are any of them capable of finally breaking through?
Danny Willett, Zach Johnson, Angel Cabrera
Thursday tee time: 8:13 a.m. (hole 10)
With a combined five major championships, these guys always seem to bring their best when it counts the most.
The Old Guard
Steve Stricker, Stewart Cink, Phil Mickelson
Thursday tee time: 2:20 p.m. (hole 1)
Mickelson is unlikely to play as he plans to attend his daughter's high school graduation, but he is still yet to officially withdraw from the tournament. Meanwhile, Wisconsin native Stricker is looking for his first major championship at Erin Hills.
Webb Simpson, Ernie Els, Lucas Glover
Thursday tee time: 8:35 a.m. (hole 1)
Simpson, Els, and Glover all have major championships under their belts, but it seems unlikely that they will make much noise at Erin Hills - unless, one of them can capture lightning in a bottle.
