The 2020 U.S. Open at Winged Foot is underway, and there are some absolutely loaded groups for what will almost assuredly be the toughest test of golf this season in southern New York. The USGA always creates interesting trios, and that's true again this year with most of the best players in the world in attendance at the 2020-21 season's first major championship.

The threesome of Tiger Woods, Justin Thomas and Collin Morikawa headlines the groups -- how often do you think Tiger has been the third-best ball-striker in his group? -- but it's far from the only tee time worth keeping an eye on this week. Rory McIlroy, Adam Scott and Justin Rose will play together on Thursday and Friday as well. So will Bryson DeChambeau, Tony Finau and world No. 1 Dustin Johnson. World No. 2 Jon Rahm is grouped with Phil Mickelson and Paul Casey.

The group that maybe most intrigues me is the Oklahoma State trio of Rickie Fowler, Viktor Hovland and Matthew Wolff. It seems unlikely that any of them would win the event this year, but all three are currently ranked in the top 50 in the world and should be expected to make the cut.
