The match, which saw goals from John Marquis, Mallik Wilks, and Danny Andrew help Rovers to a 3-1 victory, means the Saddlers suffered their fourth defeat in a row, adding to their recent woes and allowing several of their relegation rivals to close the gap.
The Saddlers did score a goal of their own, as Josh Gordon bagged his eighth of the season, but, after going two down in the opening four minutes, were ultimately unable to get back into the match, something which Keates admits is a recurring frustration.
