Serena Williams and Naomi Osaka kicked off their Australian Open campaign in a grand style on Monday as Angelique Kerber was crashed out in the first round by Bernarda Pera.
Serena Williams playing in her 100th match at the Melbourne slam was broken in the opening game but hit back immediately and kept her foot on the pedal in a one-sided contest.
The 39 year-old rallied back to smash 16 winners to defeat unseeded German Laura Siegemund 6-1, 6-1 at Rod Laver Arena.
Serena Williams who is bidding to equal Australian Margaret Court’s record for major titles will face Serbia’s Nina Stojanovic in the second round.
Naomi Osaka also cruised into the second round of the Australian Open with a 6-1, 6-2 victory over Anastasia Pavlyuchenkova in 68 minutes.
The three-time Grand Slam winner stretched her streak to 15 matches unbeaten including the US Open final dating back to 12 months.
Osaka will face Caroline Garcia of France or Slovenia’s Polona Hercog in the second round.
However, former champion Angelique Kerber lost to American Bernarda Pera 6-0, 6-4 whiles Serena Williams’ older sister Venus Williams ended her four-match losing streak at a majors with a 7-5, 6-2 triumph over Kirsten Flipkens.
Venus, 40, is the oldest woman in this year’s draw and just the sixth player in her 40s to compete at the Australian Open.
