Serena Williams powered her way past Ekaterina Makarova 6-3 6-3 to begin her quest for a seventh US Open and record-breaking 23rd Grand Slam title.
In a rematch of the 2014 semi-final, Williams prevailed in straight sets to open the night session.
Williams, who won Wimbledon in July, is aiming to win her 23rd Grand Slam title, which would surpass Steffi Graf for the most all-time in the Open era.
“I love coming out here with this New York crowd – it’s super special, and I love it here. I love you guys. Thanks so much!” the American top seed said.
“I got off to a fast start, and I didn’t want to start out slow. That’s all I could do today.
“I’m going to have to wait until tomorrow to see. I haven’t been able to play much since Wimbledon, so every day I’ll just see how it goes.
“I absolutely love the new stadium. I love the roof, it’s exciting. We’re doing great things out here.”
