Yannick Bolasie and substitute Rory Patterson scored second-half goals to plunge the Saddlers deeper into the mire and boost Argyle`s slim survival hopes.
Sadler said: "We are delighted with the result. It was a good performance and a great response following Tuesday night's defeat at Leyton Orient, which we were all bitterly disappointed with.
"We`ve got six massive games coming up and we are going to have to be at our best again at Peterborough next Saturday, but obviously we are delighted to have won this one."
