PAUL White’s second-half penalty save wasn’t sufficient for the Pics to relieve their relegation worries.
Rushall’s keeper atoned for the error that afforded the visitors the chance to extend their 1-0 advantage midway through the second half.
But that could not spark Richard Sneekes’ men into life as the Black Country outfit failed to grasp a chance to gain some upwards momentum.
The defeat leaves Rushall eight points from safety with Marine occupying the last spot above the dropzone.
Three clubs remain stuck on 26 points but games are now running out and four defeats on the spin have done little to suggest that they can move themselves out of trouble.
Sports’ skipper Mark Jones scored the only goal of the game just after the half-hour.
Pics failed to create many goalscoring opportunities with their best effort being a Liam McAlinden free-kick that went just over the bar late on as Spors’ gained revenge for their FA Cup defeat in the Fourth Qualifying Round earlier this season.
