Four missed penalties saw Saracens throw away the chance to go top of the Aviva Premiership after a 12-3 defeat against Worcester.
Sarries were missing eight players due to international duty and the Warriors started the contest brightly and were rewarded when Andy Goode fired over a penalty.
Saracens were given the chance to immediately level but Nils Mordt's 45-metre kick was off target.
However, he made no such mistake with his second attempt and drew the game level with a simple penalty.
Worcester reasserted their control and should have retaken the lead with a penalty. Goode this time off target.
The Warriors were denied the first try of the game when Errie Claassens failed to collect a clever chip ahead from Goode close to the line.
But Goode did put them back ahead as he scored his second penalty.
Mordt could've levelled but missed a kick before Goode scored a drop goal before adding another penalty to send Warriors 12-3 ahead at the interval.
On 51 minutes Mordt had another penalty chance but his effort struck the post.
Goode then missed a drop goal attempt and a penalty before Mordt was withdrawn in the final quarter.
Sam Stanley was his replacement but could do no better with the boot as he missed from 30m to deny his side a bonus point.
