The U.S. Open has arrive, and with the first two rounds of tee times released, we have some pretty unbelievable groups to enjoy over the next two days. They're highlighted by a group that includes Tiger Woods, Dustin Johnson and Justin Thomas, which will tee off from No. 1 at 1:47 p.m. on Thursday and 8:02 a.m on Friday.

The flip side of the groups includes a Phil Mickelson, Jordan Spieth and Rory McIlroy threesome that should be immense as well. They go at 8:02 a.m. on Thursday from No. 10 and 1:47 p.m. on Friday from No. 1.

But that's not all.

Jason Day, Bubba Watson and Brooks Koepka (who have a combined four major championships) will play together for the first 36 holes at historic Shinnecock. So will Rickie Fowler, Hideki Matsuyama and Marc Leishman. That trio consists of what could be the three best current golfers without a major championship.

Thursday at Shinnecock should rock as the U.S. Open returns to its roots for the first time since 2004 and its fifth-ever national championship unfolds in Long Island.
