The Scot, defending his Internazionali BNL d'Italia Masters title here, was down 0-4 in the blink of an eye, the Italian pinging balls to the corners at lightning speed in front of his home crowd.
Murray wasn’t helped by some passive play that saw him bunting the ball down the middle in the hope that Fognini might miss. Although the world number one rallied with a couple of service holds, the Italian ran the set out comfortably.
