The Exeter Chiefs beat the Leicester Tigers 19-6 to record their first win against them since 2012.
Exeter went ahead after the rolling maul led to fly-half Gareth Steenson finding himself in space to drive home across the line before brushing himself off to add the conversion to the score.
Adam Thompstone thought he had brought Leicester back into the game late in the first half with a strong try but Exeter's James Shaw prevented it with his leg dislodging the ball before it was grounded and the score was ruled out for a knock-on.
Steenson then added three points to the scoreline after the Chiefs were awarded a penalty after a knock-on but Leicester pulled back to within a try as Owen Williams split the uprights moments later.
However, Exeter increased their lead back to 10 points as Steenson hit another penalty as time expired in the first half.
The Chiefs continued to hold out well in the second half, limiting Leicester to few opportunities and keeping them at bay despite the away side's territory advantage.
Williams brought Leicester to within seven points again as he converted his second penalty of the game before England international Henry Slade missed his kick for Exeter but Steenson converted again with five minutes left to restore the 10-point lead.
Exeter thought they had extended their lead late on with a walk-on try by Jack Nowell but the play was pulled back for a pull-back on Riccardo Brugnara, who was yellow carded for kicking out in reaction and Steenson put up another three points from the resulting penalty.
The win moves Exeter into second in the Aviva Premiership as the Tigers drop to fourth.
