Serena Williams has been defeated in a major upset during the semi-finals round at the 2015 U.S. Open on Friday (September 11) in New York City.
The 33-year-old tennis player lost to Italian player Roberta Vinci – 6-2, 4-6, 4-6.
“I’m sorry… for the American people, for Serena, for the grand slam. But today is my day, sorry guys!” Roberta said in her post-match interview.
If Serena won the match, she would have went on to the finals for a chance to win the grand slam, a victory in all four of the major tournaments.
