Watson ousts Vinci in Rome

Watson broke her Italian opponent twice to claim the first set before comprehensively taking the second.

The 22-year-old world number 41, who went out in the first round of the Madrid Open earlier this month, next faces Kazakhstan’s Zarina Diyas in the clay-court tournament.

Defending champion Serena Williams received a bye into the second round and will play Russian Anastasia Pavlyuchenkova, who upset Australia’s Sam Stosur 6-4 7-5 in the shock of the day.

Germany’s Sabine Lisicki, American Madison Keys, Russian pair Daria Gavrilova and Elena Vesnina, Poland’s Agnieszka Radwanska and home favourite Sara Errani were among those to progress on Monday.
