The world number four's shot appeared to have gone with a four-over par back nine on Saturday to leave the American seven shots off the lead at the beginning of the day.But Young stormed through the front nine in 29 shots to go from three under to eight under par and added more birdies at the two par fives on the 14th and 17th coming home to move to 10 under.However, he found the sand off the tee at 18 and smashed his second shot into the face of the bunker for a costly bogey."I've played around the lead in majors enough to know that scraping out even par on a Sunday in a major championship can be really difficult. So you figure those guys at the top, somebody's probably going to make a run, but I was just close enough," said Young."Right now that's holding true. So we'll see where we are at the end of the day."Sam Burns held a two-shot overnight lead, but that vanished in three consecutive bogeys at four, five and six that dropped the American to eight under.

South Korea's Kim Si-woo moved within sight of his first major at the turn but also dropped back to eight under with bogeys on 11 and 12.New Zealand's Ryan Fox and Australian Lucas Herbert are also still in contention at seven under with six holes left to play.Defending champion Scottie Scheffler just left himself too much to do as he finished at seven under after a rollercoaster final round.The world number one's defence of the Claret Jug has been blighted by poor putting.Scheffler began the final round six back, but halved that deficit with three birdies in his opening five holes.
