Lauren Boyle impressed with her second victory at the FINA World Cup Asian circuit in Singapore overnight.
The 25-year-old wore down early leader Melanie Costa to win the 400m freestyle in 4:00.78, nearly two seconds ahead of the Spaniard who held off her compatriot Mireia Belmonte for second.
Boyle will now move on to the second of three legs of the Asia cluster with the two-day meet in Tokyo on the weekend.
This is her second win of the series over the distance, claiming the opening round in Eindhoven in August before finishing second to Belmonte at Berlin, where the Spaniard
broke the world record.
It is an outstanding start to the series for Boyle after her victory last night in the 800m freestyle, the event which she won the world title in 2012.
