Caloundra, 7 February 2011 | Rob O'Gorman

Marinko Matosevic heads a long list of Aussie men in action at this week’s Caloundra Tennis International.

The Queensland tournament is the second ATP Challenger event on the Australian Pro Tour this month following last week’s McDonalds Burnie International in Tasmania.

At No.142 in the world rankings, Matosevic is the top seed in the main draw and desperate to atone for last week’s early exit in Burnie, where he lost to Canadian Philip Bester in the first round.

“I’m very happy to go in as top seed. I’m the highest ranked player and one of the favourites,” Matosevic said. “But everyone’s very good in this tournament – it’s a strong cut. Every match is going to be really tough.”

Chris Guccione faces a qualifier in the first round and will be hoping to emulate last week’s winning run, which saw him reach the final in Burnie.

The left-hander was forced to withdraw from the title match after suffering a recurrence of the achilles injury, which kept him off-court for several months in 2010.

Teenager Bernard Tomic looms as another title threat, coming off a third round appearance at the Australian Open and semifinal showing in Burnie.

He begins his campaign against Canadian Peter Polansky and if successful, will play either John Millman or Sam Groth in the second round.

Carsten Ball is drawn to meet a qualifier in the first round while Matt Ebden takes on Japan’s Hiroki Kondo.

Other Aussies in the main draw include Brydan Klein and Greg Jones as well as wildcard entries James Lemke, Ben Mitchell, Matthew Barton and James Duckworth.
