CARNOUSTIE, Scotland -- K.J. Choi birdied the last hole to regain the sole lead of the Senior British Open after three rounds on Saturday.
The South Korean golfer takes a one-shot lead into the final round at Carnoustie.
Choi, up by two overnight, led the field by six after 14 holes. Then consecutive double bogeys pegged him back and, going into the 18th, he was tied with Richard Green, who carded a 4-under 68.
On a hole he bogeyed in the first two rounds, Choi birdied and closed with a 70.
Like Choi, Green has never won a senior major, but the Australian has finished top three in two senior majors this year.
India's Arjun Atwal was third, two strokes behind Choi at 6 under after a 67.
Atwal was two shots clear of England's Paul Broadhurst, the 2016 champion.
