Summer McIntosh wins third gold of swimming worlds as Marchand dazzles

• McIntosh swims second-fastest 200 fly in history

• Marchand wins gold but misses own world record

• Popovici adds 100m title to 200m freestyle crown

Summer McIntosh came within a whisker of breaking a long-standing world record and Leon Marchand failed to improve on a new mark he set just a night earlier, but both young guns won gold medals at the world championships in Singapore on Thursday.

Romania's David Popovici also flirted with a record on day five at the World Aquatics Championships Arena, the 20-year-old claiming a thrilling 100 metres freestyle gold to go with his 200 crown on day three.
