NEW YORK — Roberta Vinci delivered one of the biggest upsets in tennis history with a U.S. Open semi-final win over Serena Williams on Friday that ended the American's Grand Slam bid and set up a surprising all-Italian final.
Two match wins from becoming the fourth woman to win all four majors in one year, a nerve-wracked Williams crumbled as unseeded Vinci, playing in her first grand slam singles semi-final, battled to an improbable 2-6 6-4 6-4 win.
"I don't want to talk about how disappointing it is for me," a grim-faced Williams told reporters.
