Louis Oosthuizen takes a two-shot lead into the third round of the 149th Open on Saturday on the back of a record-breaking display at Royal St George's.
Runner-up in the last two majors, Oosthuizen added a 65 to his opening 64 for a halfway total of 129, eclipsing the previous best of 130 set by Sir Nick Faldo in 1992 and matched by Brandt Snedeker in 2012.
Only a bogey on the 16th prevented Oosthuizen from equalling the lowest halfway score in any major – Brooks Koepka's 128 in the 2019 US PGA – but he will be more concerned with the Claret Jug than records after the events of this season.
Already a runner-up in all four major championships, Oosthuizen took his unwanted total of near misses to six by finishing second in both the US PGA at Kiawah Island and the US Open at Torrey Pines.
But the 38-year-old South African, who won the Open at St Andrews in 2010 and lost a play-off at the same venue in 2015, is halfway towards an overdue second major after following birdies on the first, seventh, 12th and 13th with an eagle on the 14th.
At 11 under par Oosthuizen was two shots clear of 2020 US PGA champion Collin Morikawa, with three-time major winner Jordan Spieth a stroke further back and world number one Dustin Johnson on seven under.
