Worcester Warriors fly-half Duncan Weir’s penalty in the red stole victory from Saracens’ grasp at Sixways.
The Scotland international stepped up to slot wide from the left to make the final score 31-29 to Alan Solomon’s side.
Tom Whiteley kicked 19 points for the Men in Black who also saw Nick Tompkins and Marcelo Bosch grab tries.
However, Michael Fatialofa, Chris Pennell, Ted Hill and Josh Adams scores plus Weir’s boot was enough for Sixways outfit to win.
A Tompkins turnover led to the first points of the game as he stripped Ben Te’o in his own 22 and from there Sarries marched up-field with Whiteley slotting a penalty from the 10-metre.
But Worcester responded well with the game’s first try. Ethan Waller’s powerful stride deep into away territory allowed him to pop up to Fatialofa and the big New Zealander rumbled home.
Composure gained and focus reset, Matt Gallagher tore through the middle of the Warriors defence and Bosch heaped pressure on winger Adams with a monstrous boot on the Welshman’s head. This led to a second Whiteley nudge and the scrum-half was involved moments later to deny a second home score.
David Strettle was shown a yellow card for a deliberate knock-on and his vacated position meant GJ van Velze looked what was a free run to the line only for Whiteley to scamper across and drag him into touch.
Worcester continued to carry hard and earn valuable forward inches, however Manu Vunipola, on his first Premiership start, relieved the danger with an intercept and Bosch cleared to the halfway, leading to Saracens opening dot-down.
Defending with expert line speed, Tompkins rushed up in the face of the Warriors midfield and the ball sat up kindly for him following his tackle to sprint under the sticks.
The topsy turvy nature of the contest was in full flow and the hosts immediately regained their advantage. Pennell and Adams displayed neat handling on the left and the latter waltzed over.
Strettle returned for the restart and reclaimed Vunipola’s kick to get Sarries on the front foot and Whiteley nailed his third penalty of the day to send the visitors into half-time with a two-point advantage.
That became five when Whiteley added to his tally but Worcester edged ahead on the counter; Hill taking a crash ball and burrowing across the whitewash, Weir chipping the extras.
It didn’t last long as the forever-busy Whiteley’s dink bounced into the bread basket of Bosch who touched down on his final appearance for the club. A fitting send off.
Schalk Burger and Bosch were replaced soon after alongside Christian Judge meaning Andy Christie, Tom Griffiths and Billy Walker came on for their Premiership debuts and making it 12 Academy products on the pitch.
One of those, Whiteley put Sarries eight points to the good with another penalty and although Warriors made it nervy with a seven-pointer through Adams against 14-men after Ben Earl’s bin, and they clinched victory with a last-minute Weir strike.
