ROME -- Italian Premier Matteo Renzi was flying to New York to attend the first all-Italian U.S. Open final.
Renzi canceled his appointments and was flying to the United States with Italian Olympic Committee president Giovanni Malago and Italian Tennis Federation president Angelo Binaghi, a statement from the premier's office said.
News of Vinci's and Pennetta's wins topped Saturday's headlines in Italy.
"We love you," said the front-page headline of the Gazzetta dello Sport, with a "NY" inside a heart that replaced the letter "O" in "love."
The front page of mainstream daily Corriere della Sera featured photos above the fold of Pennetta and Vinci -- both of them close to tears -- next to a headline that read, "Two normal Italian girls have already made history."
After Vinci's come-from-behind victory over Williams -- ending the American's bid at a calendar Grand Slam -- Renzi tweeted in Italian: "Marvelous Flavia and Roberta!!!"
Vinci and Pennetta are both from the southern region of Puglia -- located in the heel of boot-shaped Italy.
No Italian man or woman has won the U.S. Open singles title before.
Renzi is a big sports fan and a strong supporter of Rome's bid for the 2024 Olympics.
