Glen Jackson steered Saracens to an away win over Viadana with a kicking masterclass.

Sarries fly-half Jackson showed ice-cool composure to boot 23 points, including seven penalties and a conversion, on a warm night in northern Italy.

The Guinness Premiership outfit cruised to victory over Mont de Marsan last weekend but they were forced to wait until the 70th minute to seal this win when Neil De Kock crossed.

Eddie Jones' men had fallen behind in the second minute when Viadana fly-half Charles Hore hammered home a penalty after early pressure from the hosts.

But two long-range penalties from Jackson put the visitors into a slender 6-3 lead.

Hore and Jackson exchanged penalties before the New Zealander's sixth penalty edged Saracens 18-12 clear.

Gavin Quinnell was sin-binned for the hosts and Sarries took advantage when de Kock broke free from halfway to race home before Kameli Ratuvou's last minute try clinched a 35-12 victory.
