Australian Open 2015: Stan Wawrinka, Feliciano Lopez and Milos Raonic all win

Defending champion Stan Wawrinka continued his unobtrusive progress in the Australian Open to book his place in the last 16.

Wawrinka has yet to drop a set in Melbourne and enjoyed another straightforward victory in the third round, beating Finland's Jarkko Nieminen 6-4 6-2 6-4 on Rod Laver Arena.

The fourth seed sent down nine aces and won 90 per cent of points behind his first serve to set up a clash with Spain's Guillermo Garcia-Lopez in the fourth round.

Garcia-Lopez was a similarly comfortable winner over Canada's Vasek Pospisil, beating the world No 60 6-2 6-4 6-4 to reach the last 16 and equal his best performance in a grand slam.

Fellow Spaniard Feliciano Lopez continued his charmed progress through the draw with victory over Poland's Jerzy Janowicz, the 12th seed winning 7-6 (8-6) 6-4 7-6 (7-3) to set up a last-16 contest with eighth seed Milos Raonic.

Raonic continued the theme of one-sided matches by beating Germany's Benjamin Becker - who knocked out home favourite Lleyton Hewitt in the previous round - 6-4 6-3 6-3.

The victory means Raonic has equalled his best performance at Melbourne Park after reaching the round of 16 as a qualifier in 2011. ...SkySports
