Spadea has managed to stay in the world's top 30 after a superb start to last season which saw him fly up the rankings.
World ranking: 29
Australian Open best:
2003: 1st round
The American twice reached the semi-finals in Masters Series events - Indian Wells and Monte Carlo - in March and April.
The 28-year-old also made the semis in Memphis and, along with five other quarter-finals, was impressively consistent in 2003.
That was in stark contrast to the 2000 season - when he lost 21 straight matches.
Unfortunately, it remains the most notable element of Spadea's career, and it is doubtful whether he can change that in Melbourne.
A solid baseliner, he is capable of prospering on hardcourts and reached the Australian Open quarter-finals in 1999 - his best ever Grand Slam performance.
