Harlequins have continued their unbeaten start to the campaign with a close win at Worcester.
Andy Goode put the home side ahead through three first-half penalties to Quins fly-half Nick Evans's one.
Goode added a drop-goal to his tally to extend their lead shortly after the break, before Sam Smith's try and Evans's ensuing conversion kept Harlequins in the hunt.
A penalty try against the home team in the last 10 minutes allowed Quins to kick for the two-point lead, which Evans successfully did to earn his side the victory.
