Febian Brandy's strike earned Walsall their first victory in 17 games as they claimed a home win against Colchester.
The former Manchester United striker scored the only goal of the game in the second half when he rounded United goalkeeper Mark Cousins to slot home.
And Brandy could have put the Saddlers ahead earlier in the game but dragged his low drive wide.
Jabo Ibehre went close for the U's but saw his chip over goalkeeper Aaron McCarey come back off the crossbar.
Colchester, who have now gone five games without a win, are now only two places above the League One relegation zone.
Walsall's victory, their first since they beat Bournemouth 2-1 on 29 September, takes the Saddlers five points clear of the bottom four.
