Victorian Sam Groth this week enjoyed an improvement of 22 places in the ATP rankings.

Groth is currently at world No.237, improving one place to ninth in the Australian rankings.

In a largely forgettable 2016, Groth began the season ranked 60th, but, after spending the last few months of 2015 on the sidelines due to a right foot injury, struggled to regain his momentum when the new year began.

He went 4-16 through the end of Roland Garros and dropped as low as 272nd in September, before recovering ground in recent weeks.

That’s been mainly due to some improved results on the Challenger circuit; last week he advanced to the quarterfinals in Monterrey, Mexico.

Since the US Open, he also reached the second round at Challengers in Columbus and Tiburon, both in the United States.

Another improver was Jordan Thompson, who rose seven places to No.92 after his victory at the weekend at the Vietnam Open in Ho Chi Minh City.

It is Thompson’s third Challenger title of 2016 after victories in Cherbourg, France and Anning, China.

Sara Tomic was the biggest mover among the Aussie women, rising 25 places to return to the world’s top 500.

Tomic jumped to world No.482 after some impressive results on the Pro Tour, including qualifying for the main draw in Brisbane and reaching the second round in Toowoomba.
