Michael Hoey held his nerve to edge out Wales's Liam Bond at the Riva dei Tessali and claim his second Challenge Tour title.
The 28-year-old from Belfast, who held a one shot lead going into today's final round, needed a birdie at the last to force a play-off with Bond.
Hoey, who lost his full European Tour card last year, then prevailed in the decider to claim the winner's cheque of €20,800.
Stephen Browne, Damian Mooney and Michael McGeady all missed the halfway cut.
