A Marc Newsham brace within a minute sealed a well worn win for Boston against a disjointed City team.
With seven injured or suspended players in the stands Gloucester struggled against a strong Boston side.
Boston put the battle scarred City team under pressure from the off. Spencer Weir-Daley forcing an early save from Lewis Carey collecting a loose ball and whipping in a snapshot at a tight angle.
Minutes later he tipped over a header from Nathan Stanfield.
But with Matt Rose and Darren Mullings pulling the strings in midfield City weren’t without their own chances.
Mullings fired wide on 15 minutes and headed over the bar moments later as the solid game progressed.
A free kick near the box on 27 minutes was played out by Lock to Coupe, he slammed it through the wall and Lock nipped in the bounce onto the rebound only for Rick Drury to block the shot.
On 42 minutes Coupe and Hamblin hovering around the half way line played Marc Newsham onside, and could only stand and watch as he ran the length of the pitch and slotted the ball past Carey.
A minute later and Newsham had a brace, from the spot after Mike Green was judged to have blocked the ball with his hand.
The second half started well with Dave Bird scoring a 30 yard screamer, his first goal for City, pulling the score back to 2-1 but two minutes later Ben Milnes hooking in a beautiful shot at the other end.
City fought on, with Mullings and Morford coming close but the two minute brace in the first half made all the difference as Boston move closer to the play offs.
