The Pilgrims were 2-0 victors over Peterborough Sports at PIMS Park to record only their second away league win of the campaign so far.

Leak opened the scoring with a sublime 25-yarder in the 64th minute and Mooney doubled the advantage four minutes later.

It was a hard-earned result for the Pilgrims, missing the services of suspended duo Michael Bostwick and Jordan Richards, the injured Zak Mills and Bermuda-bound Keziah Martin.

United, resplendent in purple, navy and white, were bright from the off and went close to an early lead through Keaton Ward, but he was denied by a flying Peter Crook save.

Dion Sembie-Ferris, back on loan at PSL from Scunthorpe United, blasted an effort into the side-netting for the hosts, but United ended the first half well.

Tom Edge started and almost finished a slick United counter-attack, while Ethan Sephton's 20-yarder grazed the crossbar via a deflection.

The early stages of the second half were end-to-end, but it was the away side who inched in front with 19 minutes of the half played, with Martin Woods setting up LEAK to advance and crash a bouncing 25-yarder beyond the grasp of a diving Crook.

United took a firm grip on proceedings when Jimmy Knowles rolled strike partner MOONEY into the clear and he beat Crook with a composed, low finish from just inside the penalty area.

Gregory excelled to deny Sembie-Ferris in response, while Crook got a touch on Oliver Wilson's angled effort in stoppage time, with the ball bouncing to safety off the post.
