The final round in the final major of the 2021 golf season is underway with the last 18 holes of the 149th Open Championship off and running Sunday as The R&A prepares to name a Champion Golfer of the Year for the first time in 24 months. The beauty of Summer surrounds Sandwich, England, as The Open completes its return to the picturesque Royal St. George's in Sandwich, England, for the first time in a decade.

Though there were some withdrawals before the event, this year's tournament has featured a loaded field largely controlled by one man. 2010 Open champion Louis Oosthuizen, who set a 36-hole Open scoring record on Friday, has led after all three rounds and is battling for his first Claret Jug (and major championship) in over a decade. His score of 12 under entering Sunday was just one shot ahead of 24-year-old Collin Morikawa and three up on three-time major champion Jordan Spieth.

Will Oosty pull it out? Since winning that 2010 Open, Oosthuizen has six (SIX!) second-place major finishes, including at the last two events in 2021, the PGA Championship and U.S. Open. The affable South African enters Sunday's final round as the clear favorite at 3/2, according to William Hill Sportsbook, but Morikawa (2-1) and Spieth (5-1) are both within striking distance in what should be a blistering 18 holes to a finish on Sunday afternoon (in the United States).

While attending the Open Championship can be a ton of fun, simply being able to watch golf on the game's grandest stages is an incredible treat each year. We here at CBS Sports are thrilled to bring you wall-to-wall coverage of the Open all week long.
