The youthful Blues side included a number of players that had been in action the previous evening against Kidderminster Harriers and they could have no complaints with the result.
Walsall started the game much more positively and twice went close twice in the opening five minutes.
It took Blues until the quarter-hour mark before they threatened. Wes McDonald curled an effort wide of the post and then Alex Jones tested the keeper with snap shot from the edge of the box which was saved low down.
In what were blustery conditions, Blues struggled to get through a well-marshalled Walsall defence and were largely forced to try their luck from distance.
Walsall continued to threaten and finally got the goal their play deserved when they took the lead on 79 minutes after beating the Blues off-side trap. They then doubled their tally just over a minute later following a goalmouth scramble.
Blues Development Squad Coach Richard Beale (pictured) admitted that his players didn't do themselves justice.
"We were very flat," said Beale.
"It was an opportunity for a lot of players that hadn't played as many minutes as they'd hoped to play.
"But we didn't see as much energy and aggression as we expect from them and that led to a slow tempo to our play.
"Those that do that will be the ones that go on and hopefully get in and around the First Team and those that don't will fall by the wayside.
"We didn't really create any really good chances and that came from a lack of energy and zip to our play.
"But that's taking nothing away from Walsall who were the better team on the day and I've got no problem with the result."
