(11) Juan Monaco
Monaco heads to the Australian Open on the back of the best year of his career to date, although he's unlikely to find much success at the start of 2013 on the hardcourts of Melbourne.
Having began 2012 ranked number 26 in the world and without a trophy since 2007, the Argentinian broke into the top 10 for the first time in August after claiming three titles and a month later he went on to win a fourth in Kuala Lumpur.
That last triumph was actually achieved on a hardcourt - albeit not against a particularly strong field - while his other six ATP titles have come on by far his favourite surface, clay.
The 28-year-old will be a considerable outsider Down Under, with a negative career win-loss ratio on hardcourts and a modest record at Melbourne, making it past the second round just twice and never venturing beyond the third.
Therefore 'Pico' may not be a realistic title contender here and a run to the quarter-finals would exceed expectations, but he could spring a couple of surprises along the way.
