The match, which was played in front of over 5,500 fans at Banks's Stadium, saw the Saddlers stretch their unbeaten run to five games as they defeated the promotion-chasing Grecians by three-goals-to-one.
Rory Holden's second goal of the season along with an Elijah Adebayo brace - the striker coming off the bench to steer his team to victory - saw the Saddlers deny the visitors a second-half comeback as the Grecians went home empty handed.
