Exeter Chiefs have battled to their ninth win of the season with a 32-21 victory away at Harlequins in the Aviva Premiership.
The home side took an early lead through a Nick Evans try, but Exeter hit back through Ben White.
Henry Slade slotted over three successive penalties, before he waltzed through the hosts' defence to score his team's second try in the 50th minute.
The fly-half scored two more penalties as a stunned Harlequins failed to respond, but centre Tom Hopper gave them hope with a try in the 69th minute.
However, Slade kicked a sixth penalty to relieve the pressure and confirm the win.
