World number one Jelena Jankovic and American Andy Roddick led the charge into the Australian Open second round on Monday, while Ana Ivanovic survived early tournament wobbles.
Under blazing sun, Serbia's Jankovic brushed aside Yvonne Meusburger 6-1, 6-3 in impressive fashion as she searches for a maiden Grand Slam title to silence the critics who question her ranking.
Seventh seed Roddick was equally formidable, crushing German qualifier Bjorn Rehnquist 6-0, 6-2, 6-2.
But pin-up Ivanovic struggled before downing Germany's Julia Goerges 7-5, 6-3.
Despite complaining that her feet were burning on Melbourne Park's sun-drenched rubberised surface, Jankovic kept her cool, benefiting from a brutal off-season training regime in Mexico.
"It's exciting to begin this tournament and to start with a win is always nice," she said.
"It was so hot and my feet were really burning," she added. "If I'm going to go very far I have to deal with it."
Roddick, a three-time semi-finalist here, raced through his match in just 105 minutes and said adding another Grand Slam title to his 2003 US Open win remained his "ultimate goal."
"I'm 26 so I'm not quite over the hill," he said. "I battled some injuries last year so it was kind of tough getting back and being able to train.
"(Winning Slams) is the ultimate goal and I'm excited to start in Melbourne.
