Portsmouth beat second-from-bottom Leicester City to leave the Foxes in real danger of being relegated from the Championship.
Ibane Bowat scored the game’s only goal, bundling the ball into the net at the back post from an Adrian Segecic corner.
This result leaves Gary Rowett’s side five points behind West Brom, who occupy 21st, with games against Hull City, Millwall and Blackburn Rovers still to play.
And they could be further adrift later on Saturday, with the Baggies facing Preston North End at 15:00 BST.
The Foxes have failed to win any of their past six matches and have only won 11 league games all season.
Portsmouth are now seven points clear of the relegation zone with three games to play and can no longer be caught in the table by Leicester.
