Worcester Warriors have edged out London Welsh 13-6 in Friday's Aviva Premiership encounter at Sixways Stadium.
Two penalties apiece from Gordon Ross and Alex Goode saw the two sides go in level at the break.
Ross had the chance to put Welsh in front five minutes after the restart, but his kick was off target.
The visitors were made to pay just before the hour as Semisi Taulava bundled his way over for a decisive try which Goode converted.
Ross was wayward with another penalty late on as Worcester clinched their second win in three matches.
