British sprinters make smooth progress on day seven

Having finished fourth in the 100m Freestyle final the previous evening, Fran Halsall returned to the pool for the 50m Free heats and eased through seventh fastest overall.

The British record holder - who won Commonwealth silver and European bronze in this event last season - finished third in her heat to progress in a relaxed 25.05.

Kate Haywood had to wait until day seven to compete in Shanghai but showed no rustiness as she qualified eighth fastest for the 50m Breaststroke semi finals.

The Commonwealth bronze medallist was only 0.18 off her personal best as she touched in 31.30 to finish second in her heat behind Russia's defending champion Yuliya Efimova.

Defending champion and world record holder Liam Tancock was next up in the 50m Backstroke heats and cruised into the semi finals with little fuss, clocking 25.26 to progress in 10th.

Haywood was back in the pool for the 4x100m Medley Relay heats and teamed up with Georgia Davies, Jemma Lowe and Amy Smith to put Great Britain fifth fastest into the final.

The British quartet - who guaranteed themselves a spot at London 2012 in reaching the final - finished second in their heat, just 0.03 seconds behind Australia in 3:59.65.

Daniel Fogg was the final British swimmer in action in the morning session in the heats of the 1500m Freestyle.

And while the British Gas ITC Loughborough swimmer ducked under his bronze-medal winning time from last year's Commonwealth Games, his effort of 15:13.39 saw him finish 14th overall.
