Serena Williams served 16 aces as she breezed into the second round of Wimbledon with a 6-1 6-2 victory over Anna Tatishvili.
The five-time champion, a firm title favourite and the top seed, took just 61 minutes to defeat her fellow American on Centre Court.
Williams is looking to reclaim the Wimbledon title she last won in 2012 after suffering a shock defeat to Sabine Lisicki last year.
Georgia-born Tatishvili, who in recent weeks has begun playing under the Stars and Stripes after gaining US citizenship, had a fired-up Williams across the net.
And it showed as the 32-year-old rained down one booming serve after another, hitting a peak of 117 miles per hour on the speed gun, with her might making her unplayable at times.
As well as the aces, Williams plundered a plentiful array of winners, suggesting she is playing well enough to justify her reputation as the player to beat.
At times Williams struggled to stay on her feet, and will wait until the morning to learn whether there are lingering injuries caused by repeatedly stumbling over.
"I'll see tomorrow. I fell so many times it was weird because I usually feel really good," Williams said.
"I just kept falling today but it's probably (about) getting my bearings. I didn't play much grass last year and so I think I'll be okay. Every time I step out on that court makes me want to keep coming here for years and years."
