Michail Antonio’s first-half effort proved to be enough for West Ham in a game that saw both teams spur good opportunities.
The decisive moment came on the half-hour mark when Antonio drove towards goal and curled a left-footed shot into the bottom far corner of the goal after taking advantage of Patrick Van Aanholt’s prior error in giving away possession.
In a game that started slowly the goal certainly brought the match to life and saw both sides miss efforts that should have found the net.
Mark Noble had a long range strike in the first half tipped over the bar by Vito Mannone whilst at the other end Adrian did well to stop Jermain Defoe when he turned a stinging effort around the post.
The second half saw more spurned chances with Andy Carroll somehow managing to volley against the bar from only six yards out.
Sunderland had a couple of great opportunities to level proceedings when first on 74 minutes Deandre Yedlin from the right hand byline provided a great cut back to Jack Rodwell but his effort from ten yards out was well saved by the feet of Adrian.
Rodwell then came close again but somehow managed to scoop an effort from close range over the bar.
Despite the scoreline, Sunderland were on top for good portions of the second half and should have found the net with a couple of their efforts, but will now be sweating on results of teams around them as they are still one point from safety.
