Wes has entered several superb performances since joining the club on a short-term deal last summer and had begun to attract interest from a variety of other clubs.
Scoring five goals from twenty-four all-competition outings,Wes has formed a crucial part of the Saddlers team which has recently returned to form and risen to the top half of the League Two table.
Speaking via the club's official website, manager Darrell Clarke welcomed Wes' new deal, he said; "We’re pleased to get the deal done. He’s become a fans favourite at the club and we’re looking forward working with him, There are areas he can improve but if he continues to do so then we’ll have one hell of a player on our hands."
