It was business as usual for world number one Serena Williams in the first round of the US Open on Tuesday as she faced little trouble in her 6-3, 6-3 victory over Ekaterina Makarova.
The 34-year-old, who has reached the final of all three grand slams this year, but only triumphed at Wimbledon, is looking to avenge her loss in the semi-finals at Flushing Meadows last year which ruined her chances of becoming the first woman to complete a calendar Grand Slam since Steffi Graf in 1988.
After an even opening to proceedings, Williams broke Makarova in the sixth game of the match to go 4-2 lead up before going on to serve out the set 6-3.
In the second set, Williams broke Makarova in the fifth game to edge ahead 3-2 and didn’t look back, breaking the 28-year-old once more to secure a straight-sets victory.
Williams will face Vania King in the second round, after the American beat Antonia Lottner 7-6 (2), 6-3.
It was also smooth sailing for fourth seed Agnieszka Radwanska who needed just 55 minutes to see off Jessica Pegula 6-1, 6-1.
Radwanska, who is still on the hunt for her maiden grand slam title, broke Pegula five times during their match and will face Naomi Broady in the second round after the Briton defeated compatriot Laura Robson 6-7 (4), 6-3, 6-4.
Two-time US Open champion and sixth seed Venus Williams also booked her spot in the second round after a hard-fought 6-2, 5-7, 6-4 win over Kateryna Kozlova, while 10th seed Karolina Pliskova triumphed over Sofia Kenin 6-4, 6-3.
Earlier, 11th seed Carla Suarez Navarro put Teliana Pereira to the sword, needing just 47 minutes to east past the Brazilian 6-0, 6-0.
Fifteenth seed Timea Bacsinszky was in a similar mood against Swiss Vitalia Diatchenko, winning 6-1, 6-1 in 63 minutes, while 17th seed Anastasia Pavlyuchenkova eased past American Louisa Chirico 6-1, 6-4.
Elsewhere, 2011 US Open champion and 16th seed Sam Stosur survived a second set comeback from Camila Giorgi to win 7-5, 6-7(4), 6-1. The Australian reached the fourth round of the event in 2015.
Not all the seeded players made it through though as Denisa Allertova stunned Ana Ivanovic, beating the 29th seed 7-6 (4), 6-1.
