Scotland scored the first try in Rome after 10 minutes, taking his time to pick up Hamish Watson’s long, bobbling pass to score.
Finn Russell went very close to the try line moments earlier before being hauled down, but the toll on Italy’s defenders left a huge overlap that Brown was able to exploit.
Italy had take the lead with a Tommaso Allan penalty, and Grieg Laidlaw’s missed conversion made it 5-3 to the visitors.
