Top seeded tennis player Serena Williams outplayed unseeded Russian player Ekaterina Makarova 6-3, 6-3 in the first round of the US Open here.
Williams hit 12 aces with only one double-fault in the 63 minutes it took for her to win on Tuesday.
"I got off to a fast start, and I didn't want to start out slow. That's all I could do today," said Williams, who has played just three singles matches since Wimbledon because of a sore right shoulder.
"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," she added.
