Melbourne, Australia, 30 July 2012 | tennis.com.au

Marinko Matosevic’s semifinal finish at last week’s Farmers Classic in Los Angeles has vaulted him 17 places up the ATP World Tour rankings.

Now sitting at world No.64, it’s a career-high ranking for the Victorian, who becomes firmly entrenched as Australia’s second-ranked male.

Ahead of him is Bernard Tomic, who is just 15 places higher at world No.49.

Matosevic significantly improves on his previous high of No.72, achieved five weeks ago.

The performance in Los Angeles was Matosevic’s second semifinal finish in 2012, taking his season’s win-loss record to 13-11 at ATP level.

The first came in Delray Beach in February, where as a qualifer Matosevic enjoyed a spirited run through to the final.

Incredibly, since beginning the year outside the top 200, Matosevic has shaved almost 140 places from his ranking.

His compatriot Matthew Ebden cemented his position as Australia’s No.3, rising six sports to world No.72 after reaching the second round in LA.

Other notable movers included James Duckworth, whose jump of 12 spots returned him inside the top 200 (at world No.194), and Brydan Klein, who rose 47 places to No.241 after reaching the semifinals of the Astana Challenger in Kazakhstan.
