South Korea's Im Dong-Hyun, three days after setting a world record in the ranking round, advanced into the 1/8 eliminations in the men's individual tournament following a pair of victories Monday at Lord's Cricket Ground.
The top-ranked Im, who broke his own 216-arrow record in the ranking round by shooting a 699, is legally blind in his left eye with just 20/200 vision. The Korean won five of his eight total sets Monday while managing a tie in two others.
Fourth-ranked Larry Godfrey of Great Britain also won a pair of matches to advance and, like Im, will try to move into the quarterfinals on Friday.
The United States' Jacob Wukie will play his first match on Tuesday, while fellow Americans Brady Ellison and Jake Kaminski don't go until the following day. That trio managed to win silver in team competition on Saturday.
On the women's side, No. 3 Tan Ya-Ting of Chinese Taipei was the highest seed to get underway on Monday and she advanced all the way to the 1/8 elimination. It wasn't a roll, as she survived a five-set scare from 62nd- seeded Swiss Nathalie Dielen.
American Miranda Leek won her opening-round match, but was bested by Italy's Pia Lionetti in the 1/16 elimination.
Jennifer Nichols of the U.S. is in action on Tuesday.
