Before the match Worcester were second last in the Zurich Premiership on 21 points. Below them NEC Harlequins had 20 points. Above them were Saints with 22 and Leeds with 25. The win takes the Warriors, at least temporarily, above Saints and level with Leeds.
Worcester's treasure on Friday night was the boot of James Brown. The fly-half scored 17 points in all for a victory which the Warriors thoroughly deserved.
The Worcester pack laid the foundation for the victory and it was a forward, prop Tony Windo, who opened the scoring.
By half-time Worcester led 16-9 but then André Snyman and Tim Stimpson scored tries off Worcester mistakes, both off charge-downs.
Stimpson converted his own try to make the score 16-15. But then the Brown boot started working again and right to the end their pack dominated.
