Marinko Matosevic has claimed the first ATP Challenger title of his career with victory at the $75,000 Comerica Bank Challenger in Aptos, California.

The unseeded Australian didn’t drop a set all week and claimed the final 6-4 6-2 over third seeded American Donald Young.

After knocking off top seed Rajeev Ram (world ranking 97) in the first round, Matosevic went to beat fellow Australian & Davis Cup member Carsten Ball (world ranking 120) in the semifinals and Young (world ranking 105) in the title match.

For his efforts, Matosevic takes home USD$10,800 and a bucket load of rankings points.

On Monday, he rocketed up 51 spots in the world rankings to a career high world No.159.

Matosevic has had arguably his best year to date, qualifying for the main draw of two ATP events in Sydney and Indian Wells as well as reaching the final of another Challenger event in Ojai two weeks ago
