SPECIAL ENERGY
There is always excitement on opening night at Flushing Meadows but on Monday the teeming stadium crackled with a special energy from the moment Williams appeared on court decked out in a shimmering black robe and specially designed diamond encrusted shoes.
The outfit may have sparkled more than the 40-year-old American's play but it did not matter to a jam-packed Arthur Ashe Stadium as Williams' fighting edge remained razor sharp even if her serve and ground strokes were not.
"It’s so important to give your all," Williams told the adoring crowd. "I’ve been down and out so many times, in the public eye.
"I just want people to be inspired by my story.
"I’m from Compton, California… and I made it."
Certainly there was no more fitting place to bring the curtain down on one of tennis's most phenomenal careers than in a city that has been in her corner from the very beginning, fuelling runs to six US Open crowns.
The magnitude of the moment was not lost on the 23,000 fans, including, former US president Bill Clinton, designer Vera Wang, director Spike Lee and others who packed into Arthur Ashe not expecting to see greatness but to celebrate it.
Having been world number one for 319 weeks, Williams arrived in New York ranked below 600 and unseeded.
Even with Williams far from her best the odds were stacked against the 27-year-old from Montenegro.
Playing in her 21st US Open, Williams has never lost in the first round and her victory over Kovinic was her 106th at Flushing Meadows.
While Kovinic has been enjoying the best Grand Slam season of her career reaching the third round of both the Australian and French Open, she had not won a single match since Roland Garros.
As play got underway it was Williams showing signs of nerves, piling up the double faults as Kovinic got in front 3-2.
But Williams, as she has done so many times, lifted her game when she needed to, sweeping the next four games to snatch the first set.
Now in charge, Williams would not let it slip away in the second set, breaking to go up 3-2, and with match point and the crowd on its feet, she danced in delight as Kovinic's return hit the net.
