MILAN - Italian Prime Minister Matteo Renzi dropped his busy weekend schedule and headed to New York on Saturday for the first all-Italian women's final at the US Open. Childhood friends Flavia Pennetta, 33, and Roberta Vinci, 32, will play for the women's title in the last grand slam tournament of the year. Both reached the finals with surprise victories: Vinci beat top-seeded Serena Willliams -- one of the biggest upsets in tennis history -- and Pennetta overcame second-seeded Simona Halep. The unexpected achievement dominated the front pages of many Italian newspapers on Saturday. "We love you" was the headline, written in English, in the main sports newspaper, Gazzetta dello Sport. "Two normal Italian girls have already made history." "Marvellous Flavia and Roberta!!!" Renzi wrote on Twitter.
