Serena Williams marked her return to the US Open with an impressive straight-sets win over Magda Linette on Monday.
The 23-time grand slam champion was too good for Linette in a 6-4 6-0 victory on Arthur Ashe Stadium in the opening round.
Williams, who missed the major last year as she gave birth to her daughter in September, improved to an 18-0 win-loss record in the first round of her home grand slam.
The American, seeded 17th in New York, grew into her clash with Linette, who was no match for Williams.
A break of serve in the seventh game of the first set was enough for Williams to take the opener, with Linette winning just seven points against the 36-year-old's serve.
Williams took that momentum into the second set, racing into a 3-0 lead as she dominated with her power from the back of the court.
A powerful backhand winner down the line saw Williams break again for 5-0, closing out a strong victory and setting up a second-round clash against Carina Witthoft.
