Two early goals took Walsall a step nearer promotion and pushed struggling Torquay further towards relegation.
Trevor Benjamin headed home Kris Taylor's left-wing cross after 10 minutes and five minutes later a controversial penalty earned the win.
Torquay were furious at referee Phil Joslin's verdict of a shirt-tug by Lee Mansell on Benjamin but Dean Keates made no mistake with the spot-kick.
Reuben Reid scored with a shot on the turn and Lee Thorpe almost equalised.
