Tiger, JT, Morikawa headline opening-round tee times at U.S. Open

Groups and tee times for Rounds 1 and 2 of the U.S. Open were announced Tuesday with Tiger Woods, Justin Thomas, and Collin Morikawa headlining the list.

The trio of major champions will open their week at Winged Foot on Thursday morning at 8:07 a.m. ET off the first tee. Their second-round tee time is at 1:27 p.m. on Friday.

Rory McIlroy, Adam Scott, and Justin Rose will tee off at the same time as Tiger's group but start Round 1 on the difficult 10th hole, a 214-yard par 3.

The first-round afternoon wave is highlighted by a group of bombers. Dustin Johnson, Bryson DeChambeau, and Tony Finau will launch their first drives at 1:16 p.m. on Thursday.

The USGA also included some themed groups. Jon Rahm, Phil Mickelson, and Paul Casey make up the all-Arizona State trio. Rickie Fowler, Matthew Wolff, and Viktor Hovland are all Oklahoma State alum, and three of the four Canadians in the field - Mackenzie Hughes, Adam Hadwin, and Corey Conners - will play the opening two rounds together.
