Jersey swimmer Filip Nowacki surged into the final of the 100m breaststroke at the World Junior Championships as the fastest qualifier.

The 17-year-old won the opening semi-final in 59.24 seconds, ahead of Greek Evangelos Ephraim Ntoumas in 59.77 and fellow Briton Max Morgan in 59.93.

Those three, plus Japan’s Shin Ohashi, who won the second semi in 59.72, were the only swimmers to break the one-minute mark.

Nowacki, who is chasing medals in three events at this week’s six-day championships in Otopeni, Romania, earlier won the last of nine heats in 59.84 seconds.

The 100m breaststroke final takes place on Wednesday evening.
