Melbourne VIC, Australia, 13 September 2016 |

James Duckworth has made an encouraging jump up the rankings after a successful fortnight at Flushing Meadows.

Duckworth, a wildcard into the main draw, won his first-round match in New York before going down in four sets to Jo-Wilfried Tsonga.

As a result, he leaped 22 spots to world No.173 and returned to the Australian top five.

In 2015, Duckworth peaked at 82nd, before an injury-ravaged first few months of 2016 saw his ranking plummet.

He fell outside the top 200 in mid August but has since recovered ground, thanks to winning eight of 13 matches during the North American summer hardcourt season.

An even bigger improver was Marinko Matosevic.

The Victorian soared 47 places to No.262, after reaching the semifinals of an ATP Challenger in Bangkok and then the second round at the Road to Shanghai Rolex Masters Challenger.

It is Matosevic’s highest ranking since September 2015.

At the same tournament, Sara Tomic also reached the second round, and moved up 22 places to No.494.

Ellen Perez, who won the Australian women’s wildcard play-off for a spot in the US Open main draw, jumped 77 rungs to No.647.
