Harlequins have continued their unbeaten start to their campaign with a win over Gloucester.
The away team took an early lead through a Freddie Burns penalty to put them 0-3 up.
However, Gloucester failed to hold their lead for more than 15 minutes, as Harlequins' Nick Evans followed his conversion of Sam Smith's try by scoring a penalty to take a seven-point lead.
Burns and Evans each added a second penalty before the half, following Luke Wallace's try.
Harlequins pulled away after the break. Ugo Monye scored the first of three second-half tries to give the home team a 36-point lead, as Gloucester failed to respond.
