Melbourne VIC 3004, Australia, 21 February 2017 | tennis.com.au

Matt Ebden has jumped 142 places in the latest ATP rankings following his quarterfinal run last week in Memphis.

The West Australian, in 2012 ranked as high as 61st, moved up to No.348.

It may seem lowly, but less than a month ago, Ebden was ranked 300 places lower at 648th, having lost ground following seven months on the sidelines in 2016 due to a persistent knee injury.

In the past few weeks, Ebden reached the quarters of the Burnie Challenger before a second-round finish at the ATP event in Ecuador, helping to shave his ranking even before his Memphis result.

The 29-year-old has won eight of 12 matches so far in 2017.

On the women’s side, Isabelle Wallace improved 50 places to world No.452 after winning the $15,000 ITF event in Manacor, Mallorca.

It was the second career title for Wallace, who didn’t drop a set all week.

Wallace, 21, is now 7-1 in 2017 after following up that victory with a quarterfinal run at the second straight Manacor event.

Sam Stosur remains the Aussie women’s No.1, returning to the top 20 – at No.19 – after a quarterfinal finish in Doha.
