Melbourne VIC, Australia, 24 March 2015 |

James Duckworth has entered the world’s top 100 for the first time after his impressive efforts at Indian Wells.

The 23-year-old vaulted nine places after qualifying the main draw and reaching the second round, and now sits at world No.97.

He is one of five Aussies inside the top 100, a group led by Bernard Tomic, who jumped six places to No.29 after progressing to the quarterfinals at Indian Wells.

Tomic is now just two spots way from his career-best ranking, set back in June 2012.

Looking set to join the Aussie top 100 quintet is Thanasi Kokkinakis, who surged 16 places to 108th after reaching the fourth round in the Californian desert before being stopped by Tomic in three sets.

Away from Indian Wells, plenty of other Australians were enjoying solid gains in the rankings thanks to great results at Challenger and Futures events.

John-Patrick Smith hit a career-high ranking of No.163 after winning the Drummondville ATP Challenger in Canada, leaping 32 places as a reward.

Matthew Barton, who won back-to-back Australian Pro Tour events in Port Pirie and Mildura, has this week moved up 118 places to 382nd.

Harry Bourchier, whom Barton beat in the Mildura final, improved his ranking by 153 places; he is now up to world No.619.
