Former World No. 1 Venus Williams fought a tough first round battle against Belgium’s Kirsten Flipkens. After three tight sets, the American fell hard, 4-6, 6-3, 7-6.
Finally, the two players swung it out in a tense third set tiebreak. The Belgian quickly established a lead and emerged the victor, 4-6, 6-3, 7-6.
She fell to the ground in disbelief. The Belgian had missed out on the London 2012 Games due to blood clots in her leg.
It's a huge loss for Williams, who showed promising signs earlier this year by making it to the fourth round of the French Open and the semifinals of Wimbledon. At 36, the Rio Olympics are likely her last Games.
