Ephron Mason-Clark hit a second-half double to give Darren Ferguson a winning start to his fourth spell as Peterborough manager at Port Vale.
The win lifted Posh up two places to seventh in League One, while Port Vale remained in 11th.
Mason-Clark fired narrowly wide when shown in the clearest opening of the first half.
But the 23-year-old found his range after 56 minutes when Jonson Clarke-Harris teed up Joe Ward with a deep shot across goal for Mason-Clark to stoop to turn into an empty net.
Clarke-Harris was partially off target with a header on the hour mark, but Mason-Clark got on top of Ward’s square ball quickly afterwards and only a full-length stop from Jack Stevens prevented Kwame Poku from adding a third for the visitors.
Will Norris was rarely tested after an eighth-minute save at the feet of Mal Benning and the Peterborough goalkeeper, on loan from Burnley, marked his first senior appearance in 20 months with a clean sheet.
