David Popovici continued his incredible summer of success with a stunning championship record lead-off time of 47.07 seconds to help the Romanian men to victory in the 4x100m freestyle relay at the Fina World Junior Championships in Peru.

The 17-year-old won two breakthrough senior World 100m and 200m freestyle titles in June, before claiming four golds at the LEN European Juniors in his home country.

He then repeated his 100-200m heroics at the LEN European Aquatics Championships in Rome earlier this month, but also broke a 13-year-old senior world record in the 100m by setting a new landmark time of 46.86 secs.

Popovici – who will compete in both of his two individual events at the World Juniors, but has opted against the 400m – set a new 100m championship record of 47.37 secs in the heats, before lowering that further, to 47.07.

“I’m very happy,” Popovici told Fina after the final. “Also I like to point out that we saw lots of Romanian flags so we were also fuelled by that a little.”

He was joined in the 4x100m freestyle event, on the first day of finals, by team-mates Alexandru Constantinescu, Stefan Cozma and Patrick Sebastian Dinu.

Their combined time of three minutes 18.84 secs secured their nation a first-ever relay gold medal at a World juniors.
