Serena Williams continued her Wimbledon return by moving into the third round with an emphatic 6-1, 6-4 win over Viktoriya Tomova.
The seven-time champion lost just five of 32 points on her first serve as she took a little over an hour to triumph against her 135th-ranked opponent.
Williams was unable to defend her 2016 Wimbledon title last year because she was pregnant.
Despite her ranking having fallen to 181, Williams is seeded 25th this year.
The 36-year-old American next faces German Tatjana Maria or Kristina Mladenovic of France.
