The 2020 U.S. Open is set to tee off Thursday at the Winged Foot West course in Mamaroneck, N.Y. The competition is typically scheduled for mid-June, but due to the coronavirus pandemic, the United States Golf Association had to push it back to mid-September.

As of 2019, the U.S. Open awards a $12.5 million purse, which is the largest of all four major championships and is tied for the largest of all PGA Tour events (The Players Championship also has a $12.5 million purse).

Gary Woodland is the reigning U.S. Open champion, having won his first and only major title last year at Pebble Beach. He is currently ranked 26th in the world and is at 60-1 odds to reclaim his crown. World No. 1 and FedEx Cup champion Dustin Johnson enters Thursday's play at 17-2 in the latest 2020 U.S. Open odds.

Tiger Woods has won the event three times, in 2008, 2002 and 2000.
