Aryna Sabalenka came under early pressure as she launched her bid for a third Australian Open title but the Belarusian clicked into gear and overpowered French wildcard Tiantsoa Rakotomanga Rajaonah 6-4 6-1 to reach the second round on Sunday.
The world number one arrived for the match at Rod Laver Arena as the firm favourite but found herself a break down after the opening game and looked troubled throughout the first set by the guile of left-hander Rakotomanga Rajaonah despite getting back on serve.
Sabalenka eventually found her rhythm and reasserted control, turning her initial difficulties into little more than a footnote as the 27-year-old settled into her power game to go up 5-4 and wrapped up the set with a huge forehand that her opponent returned long.
An early break in the second set helped Sabalenka go 3-0 up and there was no stopping the four-times major champion, who closed out the contest on her third matchpoint to book a second-round clash with either Anastasia Pavlyuchenkova or Bai Zhuoxuan.
