London, UK, 17 June 2014 | AAP

Former top-ranked junior Luke Saville has produced one of the biggest wins of his career by ousting top seed Thomaz Bellucci in Wimbledon qualifying on Monday.

Saville was one of four Australians progressing to the second round in qualifying for next week’s grasscourt Grand Slam.

Sam Groth, James Duckworth and Alex Bolt joined Saville in moving a step closer to a place in the Wimbledon men’s draw.

Saville, 20, defied his ranking of No.233 to down Brazilian world No.100 Bellucci 6-4 6-7(4) 6-1.

The former junior Wimbledon and Australian Open champion will next face American Rhyne Williams in his quest for a second Grand Slam main draw berth.

Big-serving Groth defeated Brit Edward Corrie 6-3 7-6(2), while Duckworth beat Argentine Juan Ignacio Londero 7-6(9) 6-2.

Bolt ousted Slovakian 17th seed Norbert Gombos 7-5 6-4.

All are bidding to join Lleyton Hewitt, Marinko Matosevic, Matt Ebden, Bernard Tomic and Nick Kyrgios in the main draw from Monday.

John-Patrick Smith, Ben Mitchell and Matt Reid were all first-round causalities.

Women’s qualifying begins on Tuesday with Ash Barty, Anastasia Rodionova and Olivia Rogowska attempting to join Sam Stosur, Casey Dellacqua and Jarmila Gajdosova in the main draw.
