Worcester substitute Michael Taylor proved the key as his side came from behind to beat local-rivals Gloucester.
Gloucester took the lead on 21 minutes when Darren Edwards netted after latching onto a through ball.
But Taylor's arrival on the hour-mark turned the game and he levelled on 70 minutes, robbing a defender and forcing the ball home.
The striker was then felled inside the area, enabling Simon Brown to convert the penalty to secure the points.

Worcester manager Carl Heeley told BBC Hereford and Worcester:
"We kept plugging away and we made a change when we brought Michael [Taylor] on.
"He has been a catalyst again as he is an impact player, but he has come on and absolutely destroyed their back four.
"He got himself a goal and won us the penalty, so those were game-changing moments."
