Melbourne VIC, Australia, 15 July 2014 |

Sam Groth has surged 24 places to world No.99 after his run to the semifinals of the ATP Hall of Fame Tennis Championships in Newport.

The latest excellent result in what has been a career-best season has seen the 26-year-old become the fifth Australian man inside the world’s top 100.

A late-blooming success story, Groth began the season ranked 172nd, but has become one of the tour’s most improved players to establish himself in the sport’s elite bracket.

At the same event where Groth recorded his career-best ATP-level result, compatriot Lleyton Hewitt won the title; Hewitt’s victory in Newport pushed him up two places to world No.41.

Also enjoying success in Newport was young Aussie Luke Saville, who this week leapt 13 places to No.171.

The 20-year-old qualified for the main draw and won his first round match before falling in the last 16 to defending champion Nicolas Mahut.

It continued a run of excellent form for Saville, who recently qualified for Wimbledon and advanced to the second round.

He has won seven of his past 10 matches.

Saville’s close friend Ben Mitchell also enjoyed a rankings boost this week thanks to success on the ITF Futures Tour.

The Queenslander jumped 22 places to world No.238 after winning the Canada F4 title in Kelowna, and stands to rise even higher after advancing to the semifinals – and building an eight-match winning streak in the process – of the Canada F5 tournament in Saskatoon.

Mitchell is nearing his career high ranking of 209th, set back in February 2012.

In the latest women’s rankings, Olivia Rogowska moved up 17 places to world No.110 following her victory last week at the $50,000 ITF event in Sacramento, California.

It was Rogowska’s first professional title outside of Australia, and puts her within striking distance of her career-high ranking of No.108, which she reached in October 2012.
