Brad Barritt's converted try broke Cherry and White hearts on Saturday as Saracens snatched a 19-17 Aviva Premiership victory at Kingsholm.
Saracens came into this one with the strongest away record in the league, and managed to come from behind late on to take the points here too.
It was a quiet enough start to the game in the opening fifteen minutes, as both sides were solid defensively.
The home side were first off the mark with a penalty, Freddie Burns kicking a long range shot. The fly-half had a chance to extend the home side's lead with another penalty, but saw his effort come back off the upright.
Gloucester were in the ascendancy though, and scored a fine try just a few minutes later. Great play from full-back Olly Morgan, who started and ended the move to leave the visitors struggling.
Saracens finally got themselves on the scoreboard after half an hour with a penalty from distance from Charlie Hodgson. However, just before the break, the away side gifted Gloucester a penalty of their own for offside, which Burns gladly converted.
The second half started a little brighter for the visitors. Although Hodgson missed a penalty chance, centre Owen Farrell took over kicking duties to kick two penalties in ten minutes for the Saracens.
Gloucester managed to keep five between them soon after though, as replacement Tim Taylor landed a placed kick.
Things were very tight at this stage, and when Tim Taylor kicked another penalty with fifteen minutes to play, the game looked over for Saracens.
However, the away side showed why they have such a formidable away record, as they came from behind to snatch victory late on. Farrell scored a penalty with ten minutes left, and when he cleverly chipped the ball through for Barritt, the centre dived under the posts, with Farrell converting.
