Despite shooting a rocky 1-over-par 73, the Swede managed to retain the lead after starting the day with a six-stroke advantage. He finished at 16-under-par 272, two shots better than David Horsey.
Horsey caught up with Andersson Hed thanks to a birdie on the 13th hole. But then his game deteriorated and he bogeyed 14 and 18 at the Royal Park I Roveri. He fell to 14-under 274, closing with a 4-under 68.
Peter Gustafsson of Sweden carded a 6-under 66 to rally into a third place tie with Chris Wood (70) and Nicolas Colsaerts (70) at minus-12.
Ignacio Garrido of Spain posted his second straight 70 Sunday to secure sixth place at 11-under-par 277.
