Federico Dionisi scored twice as Frosinone beat Empoli 2-0 to record their first Serie A victory.Dionisi bagged his brace inside 13 second-half minutes to help Roberto Stellone's men break their duck at the sixth attempt against an Empoli side who ended the game with 10 men.After Empoli had the better of the first half, Dionisi opened the scoring just before the hour mark, slotting home from the rebound after Lukasz Skorupski had saved brilliantly from Daniel Ciofani.And Dionisi added his second in the 71st minute, firing high into the top of Skorupski's goal after latching on to Mario Rui's poor backpass.Saponara earned a straight red six minutes later for remarks made to referee Marco Guida.
