Serena Williams had the entire US Open crowd behind her when she took to the court in the first round of what will likely be her final career Grand Slam tournament.
And she had a classic night.
Dominating Montenegro's Danka Kovinić in straight sets 6-3, 6-3, Williams showed she is still a force to be reckoned with, hitting some shorts with the incredible accuracy she has displayed throughout her career.
The 40-year-old tennis legend had nine cases and at one point had won 11 straight points and four straight matches. While Kovinić struggled throughout the match, Williams took advantage of her size and showed why she is considered one of the best in the world, sprinting to return drop shots at the net and knocking the ball into the opponent's side at every opportunity.
Gayle King, who was on the court to introduce Williams to the microphone, wondered if Williams would actually stay retired because she looked like her old self.
