Arizona Tribune - MacNeil shatters 100m fly record as two more relay bests set at short course titles

A third record tumbled in the final race at Melbourne with Australia and the United States finishing in a dead heat to jointly set a new best time in the men's 4x100m medley.

Australia's Kaylee Mckeown also wrote a slice of history by winning the 200m backstroke to become the first female ever to hold the short course, long course, Olympic and Commonwealth titles in the same event simultaneously.

Defending champion MacNeil was behind Torri Huske as they turned for the final 25m lap, but powered home in 54.05 seconds to demolish the previous mark of American Kelsi Dahlia by over half a second.

The USA's Huske took silver ahead of Sweden's Louise Hansson.

It was MacNeil's second world record of the meet after breaking her own 50m backstroke best on Friday.

South African veteran Chad Le Clos made it a butterfly double by taking out the men's 100m title in 48.59 to go with his 200m crown.

It was his fifth world crown over 100m to go with the ones he won in 2012-14-16-18.

Backstroke queen Mckeown led from the start to clock 1:59.26, shy of her own world record but ahead of American Claire Curzan and Canada's Kylie Masse.

In the men's race, Ryan Murphy also led all the way to take it out in 1:47.41 and cement his status as a great after also claiming the 50m and 100m titles.

Lithuania's Ruta Meilutyte, who broke the world record in the semi-finals, was too strong in the women's 50m breaststroke, coming home in 28.50. South Africa's Lara van Niekerk won silver and American Lilly King bronze.

Among the men, Nic Fink edged Italy's Nicolo Martinenghi in 25.38, adding to the American's 100m breaststroke title. But Britain's Adam Peaty only managed sixth.

World record holder Siobhan Haughey of Hong Kong successfully defended her 200m freestyle crown in 1:51.65, while Sunwoo Hwang stunned a top field to clinch the men's gold in 1:39.72.

The South Korean, swimming in lane eight, held off Romanian sensation David Popovici and British Olympic champion Tom Dean.

Culminating the six-day meet, the American team of Curzan, King, Huske and Kate Douglass smashed their own 4x100m medley relay record when they surged home in 3:44.35 ahead of Australia and Canada.

The feat was matched by the men with Australia and the United States cracking a record that had stood since 2009 to jointly win gold in 3:18.98.

The United States finished top of the medal table with 17 gold, 13 silver and six bronze ahead of arch-rivals Australia with 13-8-5.
