Saracens had first use of the Brookfield Road slope and playing with a confidence that belied their lowly position in the league table, they opened the scoring with an unconverted try after just five minutes.
Chosen were being denied any possession and ten minutes later Saracens added a second unconverted try to extend their lead but Chosen hit back and finally opened their account with a good unconverted try from centre Ryan Rennebach.
With half time approaching, Chosen took the lead when second row Dean Barnard barged his way over after a driving maul and number ten Andy King added the conversion.
Just three minutes into the second half Saracens re-took the lead with their third unconverted try and it was another fifteen minutes before Chosen went back in front when number eight Tom Harvey picked up from the back of a scrum twenty metres out and raced towards the line selling a couple of dummies before diving over for the try converted by King.
Next to score for Chosen was replacement centre Scott Claridge whose try gave his side their four try bonus point with King adding the extras for a 26-15 lead. King then slotted a penalty goal to make it 29-15 but Saracens were not finished and a last minute unconverted try ensured that they took a single bonus point from the match.
