Top-seeded Errani routs Cohen in Palermo opener
It was a welcome return to red clay courts for Errani, last year's French Open runner-up, after losing to Puerto Rican teenager Monica Puig at the All England Club.
Errani won this tournament in 2008 and 2012.
In the second round, Errani will face either 2012 runner-up Barbora Zahlavova-Strycova or Kristyna Pliskova.
In Monday's only other main-draw matches, seventh-seeded Silvia Soler-Espinosa of Spain held off Mathilde Johansson of France 6-4, 1-6, 7-5, and Italian wild card Corinna Dentoni rallied past Carolina Garcia of France 5-7, 6-4, 6-4.
