The Peterborough United Under 21s drew 0-0 with Birmingham City Under 21s at St. Andrew's @ Knighthead Park on Friday afternoon with Ryan Semple's side maintaining their cushion from the Blues in the league table.
It was a game of few clear-cut opportunities with goalkeeper Will Blackmore making a couple of decent stops in the first half, keeping out Frank Tattum after a mazy run from the Blues front man.
The Blues had penalty appeals waved away on 17 minutes after Pendleton took a tumble in the box, but the official was unmoved.
Blues goalkeeper Will O'Sullivan made a double save to keep out Donay O'Brien-Brady and Eddie Fox on 35 minutes.
Posh substitute Patryk Sykut forced O'Sullivan into a smart save 12 minutes into the second half while Menzi fired wide at the other end.
