Under-pressure Manuel Pellegrini earned a stay of execution as West Ham boss thanks to a narrow Premier League win at Southampton.
Sebastien Haller netted his first goal since early October in the first half at St Mary's to guide the Hammers to just their second win in 12 outings.
Michail Antonio was the star of the show for the visitors and saw his own effort ruled out for handball by VAR.
The result takes West Ham up to 15th and four points clear of Southampton, who remain in the bottom three after back-to-back defeats.
