Phil Mickelson takes a one-shot lead into the final round of the US PGA Championship as he bids to become the oldest major winner following a remarkable Saturday at Kiawah Island.
The American, 50, made a fast start, with five birdies in 10 holes to open a five-shot lead on the Ocean Course.
But that advantage was wiped out as Brooks Koepka and Louis Oosthuizen drew level before dropping shots late on.
Koepka sits one back at six under, with Oosthuizen at five under par.
Five-time major winner Mickelson eventually signed for a two-under-par 70 to keep himself in pole position on seven under par.
He won the last of his majors at the 2013 Open at Muirfield and victory this week would see him take the record of oldest winner from Julius Boros, who won this title in 1968 at the age of 48.
“I’m enjoying it and playing well, I made some good swings played some good shots and I’m really having a lot of fun,” said Mickelson.
