Sunderland moved off the bottom of the Premier League, and a point from a position of safety, with victory over Watford at the Stadium of Light.
Following a first half of few chances, Patrick van Aanholt scored the only goal of the game shortly after the break.
Adnan Januzaj slid a lovely ball to Jermain Defoe, whose low cross was touched by Van Aanholt, who then swivelled and shot in off the post from six yards.
Troy Deeney had a chance to equalise when he met a Nordin Amrabat cross, but his header flew wide.
Daryl Janmaat and Odion Ighalo also had late efforts for the visitors saved by keeper Jordan Pickford, as Watford slipped to a fourth defeat in five games.
