(CNN) -- Fourth seed Andy Roddick launched his Australian Open build-up in style when he raced past Spain's Ivan Navarro 6-1 6-3 in 61 minutes at the Qatar Open on Monday.
American Roddick is determined that 2009 will not see a repeat of last year's injury problems.
The aggressive American, making his first appearance in Doha since losing in the second round on his 2004 event debut, fired eight aces and hit 30 winners against 11 unforced errors and broke serve four times.
Roddick is desperate to recapture the form that saw him defeat all three Grand Slam champions -- Rafael Nadal, Novak Djokovic and Roger Federer -- last year before injuries took their toll.
"Last year I was just going from the training table straight on to the court," Roddick said after reaching the second round.
"I was going to do everything to play Wimbledon and I shouldn't have and I was advised not to; I was hurt in Cincinnati and tried to play LA."
French No. 5 seed and 2006 runner-up Gael Monfils ousted Jan Hernych 6-2 6-2 with hit nine aces in his 55-minute match.
The 22-year-old Monfils is making his fourth appearance in Doha and now faces compatriot Nicolas Devilder who won 6-0 6-3 against Abdulla Hajji -- a wildcard from Qatar.
Romanian Victor Hanescu had a 6-4 6-2 victory over Viktor Troicki and Sergiy Stakhovsky of Ukraine also advanced, knocking out Christophe Rochus 2-6 6-3 7-6.
Federer, Nadal and Andy Murray begin their campaigns on Tuesday.
