Biggest movers: Ebden makes big impact in ATP rankings
Matt Ebden was the biggest improver in the ATP rankings during 2017, soaring more than 600 places to return to the world's top 100.
Matt Ebden has risen to world No.80 after his victory at the ATP Challenger tournament in Toyota, Japan.
The West Australian rose 18 places after his latest victory, his second Challenger title in his last three events.
It continues an extraordinary rise for Ebden, who began the season ranked 699th and was the biggest rankings improver of all players on the ATP World Tour in 2017.

He also enjoyed success at tour level, reaching the ATP Newport final and the quarters in Memphis – both times as a qualifier – and qualifying for the main draw at another four ATP events.
John Millman was another improver, with the Queenslander rising 14 places to No.165 after reaching the semifinals in at the Toyota Challenger. He fell to Calvin Hemery, who in turn went down to Ebden in the final.
Teenager Alex De Minaur jumped 16 places to world No.210 thanks to a quarterfinal finish at the Challenger event in Brescia, Italy, staged on indoor carpet. De Minaur ultimately lost to 162nd-ranked Mirza Basic of Bosnia.
Max Purcell, meanwhile, jumped 19 places to a career-high ranking of 263rd after advancing to the quarters in Toyota, where he lost to Millman.
Andrew Whittington also moved up 19 spots, and like Purcell was a quarterfinalist in Toyota. He currently sits at world No.290.
On the WTA list, Queenslander Priscilla Hon improved 17 places to world No.214 after qualifying for the WTA 125K event in Taipei and then reaching the second round.
Hon won three straight matches before falling in the last 16 to eventual champion Belinda Bencic.
