Australian archer Taylor Worth shot a personal best score in the Olympic ranking round on Friday as legally-blind South Korean superstar Im Dong Hyun smashed his own world record.
Worth was sitting in ninth place at the halfway stage of the ranking round, before tailing off in the second half of the competition at Lord's.
His PB of 668 - 10 higher than he had ever shot in competition before - left him in 23rd place overall.
The 21-year-old from Perth will take on British archer Alan Wills in the first round of match play early next week.
"There were no nerves," said Worth, who was making his Olympic debut.
"I felt excitement.
"I was ready to compete and have fun and show the world what I've got.
"I opened my first round with 58 (out of 60) and it could have been 59 but I lost a few points from some really tough line calls from the judges.
"I shot fantastically this morning.
"The second round was still OK, still a good score, but not good enough."
Im, a two-time Olympic gold medallist in the team event, shot 699, bettering his previous world record of 696 set earlier this year in Turkey.
Korean archers swept the top three spots in the ranking round.
"They've broken the world record twice this year already and a couple of times last year," said Worth.
"I'm used to those announcements coming over the PA system.
"What they do is just phenomenal - the scores that they shoot and the way that they shoot is unbelievable.
"That 699 is near perfect shooting."
Im has only 20/200 vision in his left eye and 20/100 in his right eye but has no trouble honing in on the bulls eye.
He was also part of a record in the team shoot.
Alongside Kim Bubmin and Oh Jin-hyek he helped register a 216-arrow total of 2,087 - smashing the world record by 18 points.
Kim also broke the existing individual world record with his score of 698.
