Roberta Vinci has delivered one of the biggest upsets in tennis history, beating Serena Williams at the US Open.
Unseeded Vinci – playing in her first grand slam singles semi-final – battled to a 2-6, 6-4, 6-4 win.
For world number one Williams, who was bidding to become only the fourth woman to win all four majors in the same year, it marked the first time she lost to Vinci in five career meetings.
Vinci took advantage of some loose points from the American, with inspired play and determination to snap Williams’ streak of 33 consecutive match wins in the grand slams.
Vinci will now take on Flavia Pennetta in an all-Italian final.
