The South African posted a bogey-free, 6-under-par 64 to take the first-round lead at the Open Championship at Royal St. George’s in Sandwich, England, one shot better than Jordan Spieth and Brian Harman.
Oosthuizen’s only major victory came at the 2010 Open at St. Andrews, but he has six runner-up finishes in majors — including this year’s PGA Championship and U.S. Open.
“It depends if you lost it or someone else beat you,” Oosthuizen said of getting past near-misses. “I think in both of those I was beaten by better golf at the end there … I tried to take a few days and just try and forget about it and see if I can get myself ready for the next one.”
The trio of Harman, Canadian Mackenzie Hughes and South African Dylan Frittelli, grouped together for the first two rounds, all went low. Harman birdied No. 18 to tie Spieth at 5-under 65 and Hughes and Frittelli each shot 4-under 66. Webb Simpson, Frenchman Benjamin Hebert and 48-year-old Stewart Cink also joined a tie for fourth at 4 under.
Oosthuizen landed his tee shot on the par-3 16th inside eight
