The Open: The 2021 edition starts on Thursday, and the golfer pairings for the tee-off are already out

U.S. Open winner Jon Rahm will tee off alongside 2019 Champion Golfer of the Year Shane Lowry at the 2021 Open Championship on Thursday.

Golf news:

Spaniard Rahm won his maiden major at Torrey Pines, edging out Louis Oosthuizen by one stroke, and is among the favorites to prevail at Royal St George's this week. 

Lowry was a popular winner when golf's oldest major was held at Royal Portrush two years ago, with the 2020 event having been cancelled amid the coronavirus pandemic.

The Irishman, whose trio goes out at 09:58 local time and also includes 2010 victor Oosthuizen, will seek to become the first man to defend the Claret Jug at the Kent links since Harry Vardon in 1899.

Any superstitious players might have hoped to be drawn in Branden Grace's group, as he has played with the eventual winner in his first two rounds at each of the previous two Opens.

The South African featured with Francesco Molinari at Carnoustie in 2018 and Lowry in Northern Ireland the following year. 

Jordan Spieth, a winner in 2017, and 2020 U.S. Open champion Bryson DeChambeau are the lucky pair, with that group teeing off at 09:25.

Four-time major champion Rory McIlroy will head out in the afternoon with Patrick Reed and Cameron Smith, while world number one Dustin Johnson starts his bid for a first Open title at 10:20 with Will Zalatoris and Justin Rose for company.

Brooks Koepka is an 08:45 starter and the star attraction of a threesome that includes Jason Kokrak and Garrick Higgo.

Darren Clarke, who prevailed when last Royal St George's last hosted in 2011, is an 08:25 starter alongside Bernd Wiesberger and amateur Joe Long.

The action will begin at 06:35, with English trio Richard Bland, Andy Sullivan and Marcus Armitage having the honor.
