David Moyes's side claimed their fourth win of the season thanks to a battling performance at home against the Hornets
After a run of three wins in four games kick-started Sunderland's lacklustre start to the campaign and lifted them off the bottom, back-to-back defeats against fellow relegation candidates Swansea City and league leaders Chelsea had sent them back down to 20th position.
Amrabat came close to a sensational early opener when he lashed a volley from the edge of the box, but Pickford sprung to his right to tip it over.
Miguel Britos was unable to blame a similar intervention for failing to convert in the 26th minute when he headed Holebas' free-kick wide from point-blank range, though the final touch may have come off former Sunderland defender Younes Kaboul.
Watford replaced the injured Sebastian Prodl with Kabasele after the half-hour mark, and the Belgian courted controversy before half-time when he went down dramatically after a collision with Victor Anichebe.
The atmosphere in the stands began to turn sour and Van Aanholt failed to take a chance to give the home supporters something to celebrate in stoppage-time, shooting straight at Heurelho Gomes, making his 150th Premier League appearance, at his near post.Manager David Moyes would have been fearing a similar result when only a save of the utmost brilliance from Jordan Pickford stopped Nordin Amrabat's volley from finding the top-left corner in the second minute.
Substitute Christian Kabasele was unable to clear Jermain Defoe's right-wing cross adequately and Van Aanholt span over the ball and found the back of the net via the upright with a first-time finish. The Black Cats took on a defensive approach in the closing stages and dug in for the win, moving above Swansea and Hull City and just one point adrift of safety, while Watford have slipped down to 12th.
