Andy Cook netted the only goal of the game at Kingfield and, despite the striker seeing red later in the game, Tranmere picked up another three points.
With the rest of the top ten either in the FA Trophy or without a League fixture, the victory moved Rovers up to fifth.
Mellon says the play-off places are where Tranmere belong but the boss was frustrated that his side didn’t make Saturday’s scoreline more flattering.
He told the club’s YouTube channel: “We’re disappointed we didn’t score a few more but very pleased we’ve won. We had five really good chances we should have scored.
“If you’re going to be successful, when you’re given opportunities like we were today, you’ve got to take them.
“It’s good for us to be back into the play-offs, it’s where we need to be. I’ve never hidden away from the fact that a club like Tranmere with the quality of player we have should be up at the top end, challenging the front-runners.
“We haven’t been doing that so far this season but we’re getting back in there. We’ve got a lot of experience in the squad, we know what it takes to get results at this stage of the season and use that to keep chalking up victories.”
