David Connolly struck in the second half to give Portsmouth a vital victory against Tranmere Rovers in League One.
Pompey went ahead when striker Connolly tapped Yassin Moutaouakil's low cross home from two yards out.
Rovers came closest to equalising when Ash Taylor's header went wide of the post late on.
Pompey's third home win in a row leaves them three points from safety while Tranmere have now dropped out of the top six.
VIEW FROM THE DRESSING ROOM
Portsmouth caretaker manager Guy Whittingham told BBC Radio Solent:
"I don't think [Pompey keeper] Simon Eastwood had much to do whatsoever.
"They put a lot of balls in our box and all of them; Gabor Gyepes, Sam Sodje, until he came off, and Ricardo Rocha, when he came on, defended magnificently.
"It was important that we tried to get people behind the ball and didn't necessarily go off looking for that second one to kill them off. If it came great, but we're winning the game, let's make sure we don't concede."
