American Brian Harman stormed into a five-shot lead at The Open on Friday after a faultless 65 left him on 10 under par as bigger names struggled to keep pace.
Home favourite Tommy Fleetwood leads the chase as he battled to an even-par round on Friday to remain in the hunt for his first Major.
Rory McIlroy is best-placed among the pre-tournament favourites at one under as world No 1 Scottie Scheffler and defending champion Cameron Smith needed miraculous shots at the 18th to make the cut.
South African amateur Christo Lamprecht, who shared the lead after a first-round 66, carded 79 on Saturday to slip to three over (T62).
Thriston Lawrence is the best-placed South African heading into the weekend on one under (T11), followed by Christiaan Bezuidenhout and Louis Oosthuizen on two over (T39).

Harman surged to the top of the leaderboard at the Royal Liverpool course thanks to long birdie putts at the 2nd, 3rd and 4th before his chip into the par-five 5th hit the flag to tee up a simple putt for a four.
A run of 12 consecutive pars followed before a spectacular eagle at the last.
The world No 26 has never won a Major but was sixth at last year’s Open at St Andrews and was joint runner-up at the US Open in 2017.
“I’ve had a hot putter the last couple of days so try to ride it through the weekend,” said Harman. “I felt kind of freed up on 18. I made probably my two best swings of the day and got up there to 12 to 15 feet for eagle. Just played a really nice hole.”
Barring a collapse over the weekend, the 36-year-old will take some catching, with the sport’s biggest stars failing to fire.
McIlroy believes he is still in with a chance of ending his nine-year wait to win a Major at the scene of his only Open victory, in 2014.
The Northern Irishman, benefiting from more forgiving bunkers, birdied the 5th to move to two under on the day after tournament organisers reacted to criticism from players that the sand traps were too tough during Thursday’s opening round at Hoylake.
Greenkeeping staff were instructed to build up the edges to allow more balls to roll back into the centre of the bunkers.
However, the world No 2 dropped two shots on the back nine before a birdie at the last.
“I might be nine back, but I don’t think there’s going to be a ton of players between me and the lead going into the weekend,” said McIlroy, who is currently tied for 11th.
“If I can get to three, four, five under par tomorrow going into Sunday, I’ll have a really good chance.”
Scheffler has been a model of consistency on the PGA Tour all year, but he came perilously close to missing the cut for the first time in 21 tournaments, ending with a four-over-par round to be three over for the tournament.
Needing a birdie at the par-five last, the 2022 Masters champion got up and down from a difficult lie in the greenside bunker to make a four.
Smith went one better as a remarkable second shot at the 18th set up an eagle to move to two over.
Masters champion Jon Rahm is also at two over after carding a round of 70.
Austrian Sepp Straka produced a remarkable run of six birdies in the closing seven holes to go third at four under.
Australia’s Jason Day is the highest-placed Major winner on the leaderboard at three under, alongside compatriot Min Woo Lee and India’s Shubhankar Sharma.
But the threat from the group of players now regularly plying their trade in the Saudi-backed LIV Golf series is fading after PGA Championship winner Brooks Koepka double-bogeyed the 18th to slip to three over.
