Aaron Mclean claimed the goal he craved against the team that released him five years ago four minutes after the break before Craig Mackail-Smith bagged his second of the game on 67 minutess.

Mclean's turn and shot from the edge of the box was a wonderful moment for the former Orient player, but he was just as pleased when Mackail-Smith tapped in from close range after fine work from George Boyd.

Mackail-Smith had opened the scoring two minutes before the break with a superb individual effort which involved a dash from the half-way line and a superb curled finish.

Posh could have had more goals as Mclean missed a tap-in and Mackail-Smith side-footed wide from eight yards.

Mackail-Smith had spurned three half chances in the opening 10 minutes before visitors Leyton Orient fought back.

Wayne Gray hooked their best opportunity wide on the half hour after muscling his way past Chris Westwood.

Posh recalled Shane Blackett at left-back. He replaced Tom Willians who dropped to the substitutes' bench in the only change from the team defeated at Bristol City in the Carling Cup on Tuesday.

Winger Chris Whelpdale recovered from a bout of sickness to take his place on the bench for the visit of Leyton Orient.
