Williams wins fourth Italian Open crown

Rome - Serena Williams claimed her fourth Italian Open crown in Rome on Sunday with a 7-6 (7/5), 6-3 final defeat of American compatriot Madison Keys.

It was the first all-American WTA claycourt final since Williams beat her older sister Venus to win her maiden French Open title in 2002.

Williams, who pulled out injured from last year's event, was adding to her previous wins in Rome in 2002, 2013 and 2014.
