While not as innovative or theme-based in previous in year, there are still are some blockbuster groups for the first two days of the 2015 U.S. Open. As usual, the USGA delivers with must-watch groups for fans.
Check out the full 2015 U.S. Open first and second round tee times, but here's a look at our seven groups to watch on Thursday and Friday:
Phil Mickelson, Bubba Watson, Angel Cabrera (Round 1: No. 1 at 7:33 a.m. PT, Round 2: No. 10 at 1:33 p.m. PT) -- Mickelson is a sentimental pick to finally capture the Open after six career runner-up finishes, including in 2013 at Merion. He's finished second in the last two majors. Watson is a two-time Masters champion, while Angel Cabrera has both an Open and a Masters title.
Jordan Spieth, Jason Day, Justin Rose (Round 1: No. 1 at 2:17 p.m. PT, Round 2: No. 10 at 8:17 a.m. PT) -- The Masters champion? Check. A Masters co-runner-up and former U.S. Open champion? Check. A guy who could've won both by now? Check.
Tiger Woods, Rickie Fowler, Louis Oosthuizen (Round 1: No. 1 at 2:28 p.m. PT, Round 2: No. 10 at 8:28 a.m. PT) -- Woods draws Players champion Rickie Fowler and 2010 Open champion Louis Oosthuizen. So, two guys who have won the last three Open Championships played at St. Andrews and the guy the USGA thinks will win this year?
Dustin Johnson, Adam Scott, Sergio Garcia (Round 1: No. 10 at 8:17 a.m. PT, Round 2: No. 1 at 2:17 p.m. PT) -- While Scott and Garcia are not playing their best golf, they're compelling players. However, the headliner is Dustin Johnson, who is one of my picks to do well in this Open.
Martin Kaymer, Gunn Yang (a), Rory McIlroy (Round 1: No. 10 at 8:28 a.m. PT, Round 2: No. 1 at 2:28 p.m. PT) -- Can Rory McIlroy make it five majors? After thousands of miles of travel in a busy stretch caught up with him, will he be refreshed at Chambers Bay? Martin Kaymer hasn't been the same guy since winning the U.S. Open at Pinehurst No. 2. What kind of defense will he have?
Patrick Reed, Chris Kirk, Jamie Donaldson (Round 1: No. 10 at 8:39 a.m. PT, Round 2: No. 1 at 2:39 p.m. PT) -- Yeesh, the USGA paired Kirk, who went to Georgia, and Reed, who went to Georgia before being asked to leave, going to Augusta State and crushing Georgia's dreams as part of back-to-back NCAA championships. Jamie Donaldson is there because he's the guy that clinched the Ryder Cup where Reed starred and Kirk wasn't there because of a display of ambivalence about a captain's pick.
Webb Simpson, Keegan Bradley, Kevin Na (Round 1: No. 10 at 8:50 a.m. PT, Round 2: No. 1 at 2:50 p.m. PT) -- These guys are all interesting characters, but in the rare themed group this year, the USGA put perceived slow players together.
