Darren Ferguson piled praise on his “relentless” Peterborough players after they followed up EFL Trophy success by boosting their automatic promotion bid.

Posh jumped to within six points of second-placed Derby – and also boast two games in hand – by brushing aside struggling Vale.

Joel Randall broke the deadlock in the final seconds of the first half with a blast that took a double deflection on its way past Connor Ripley after Harrison Burrows’ short corner.

EFL Trophy final hero Burrows doubled the advantage from the penalty spot 11 minutes into the second half and the Posh captain was again the architect when his 86th-minute cross was headed into his own net by Alex Iacovitti to compound Vale’s misery as they dropped back into the bottom four on goal difference.

Delighted Posh boss Ferguson said: “That is as well as we have played at home for a long time.

“It was a really good performance from my team… mature, confident, some great football and a clean sheet.

“We didn’t panic when the first goal took a while to come and then we had complete control in the second half.

“I was really pleased with the result but the manner of the performance at this stage of the season is what delighted me the most.

“People might have wondered what we would look like after Sunday but we were so fresh physically and running all over them.

“These lads are relentless. I have to give them and the staff a lot of credit.

“We know Derby drew and dropped points but we just keep looking at the next game. I’ve already watched Oxford today and we’ll look no further ahead than that on Saturday.”

Vale boss Darren Moore admitted: “It was a difficult night for us.

“If we could have got to the break with the scores level, it might have created a bit of anxiety around the place.

“But the first goal on the stroke of half time really changed my team-talk and gave us a mountain to climb in the second half.

“Peterborough are an excellent and free-scoring team with a lot of attacking options and move the ball really well. Up to a point, the boys stuck to the gameplan to nullify and contain them well.

“It’s just disappointing to concede the first and second goals in the manner we did from corners as we’d worked on that.

“The first goal took two deflections and the second one is a switch-off at the far post which leads to a penalty.

“The third one is then an own goal but I’ve got no complaints in terms of the commitment and energy the boys showed.”

Peterborough boosted their automatic promotion hopes with a 3-0 triumph that sent Port Vale plunging back into the relegation zone.

The hosts ended a frustrating first half on a high when Joel Randall’s 25-yard thunderbolt sailed past helpless keeper Connor Ripley – courtesy of a double deflection off Vale men Rhys Walters and Alex Iacovitti – to hand them the lead seconds before the break.

Randall, Ephron Mason-Clark, Ricky-Jade Jones and Kwame Poku had all squandered good chances before Ripley pulled off a fine save to deny Archie Collins, but the following corner – taken short by captain Harrison Burrows to Randall – led to Posh hitting the front.

Burrows followed up his EFL Trophy final heroics with another goal as Posh doubled their lead 11 minutes in the second half.

The captain struck for the 12th time this season when he sent Ripley the wrong way from the spot after Ryan Loft’s pull on Josh Knight.

And Burrows was again involved when Posh put the result beyond doubt in the 86th minute as his left-wing cross was headed into his own net by the unfortunate Iacovitti.

Vale fell back into the bottom four on goal difference as they failed to manage an attempt on target until second half stoppage time when substitute Uche Ikpeazu’s blast was spectacularly tipped over by Jed Steer.

Alex Iacovitti has thanked Ross County for “an incredible three years” after his departure from the Staggies was confirmed.

The 25-year-old former Scotland Under-21 defender moved to the Highlands from Oldham in 2020 and made 116 games appearances for the Dingwall club, scoring 12 goals.

Iacovitti is leaving County, who survived in the cinch Premiership following a dramatic play-off victory over Partick Thistle, under freedom of contract.

“Firstly I’d like to place on record my thank you for an incredible three years at the club,” he said in a statement on the Staggies’ website. “I’ve loved my time in the Highlands and was happy to call it home for this period.

“The supporters were excellent throughout my time here and they will always hold a special place in my heart for how they have treated me.

“The players I played with at the club are also a top bunch of lads, unfortunately I was unable to play a part in the play-offs due to an injury I had played through that eventually got the better of me.

“I was absolutely delighted the club secured their Premiership status, where they belong.

“I wanted to thank all of you for your support throughout and wish you all and the club the very best for the future. I’ll be back to watch a game as a County fan in the future!”

County will announce full details of their retained/released list in due course.
