Daichi Sawano, who finished eighth at the world championships in Helsinki last month, won the men's pole vault as Japan increased its gold medal tally to three after three days into the four-day event.

Kanemaru overwhelmed the field as the 17-year-old from Osaka crossed the line in 46.04 seconds at Incheon Munhak Stadium, finishing 0.44 ahead of runnerup Ampath Amarasekara Dodampe of Sri Lanka.

Sawano secured victory by clearing 5.40 meters but had to be content with the record after picking up an injury to his left palm when his pole broke during his second attempt at 5.60.
