Wolves took another huge step towards promotion after a routine 2-0 win against Peterborough.
Goals from Danny Batth (47) – his second of the season – and Dave Edwards (68) put Kenny Jackett’s side up to 90 points, 12 clear of Rotherham in third after they won 4-3 at Gillingham.
It means Wolves still need seven points to be mathematically sure of a return to the Championship.
But in a dominant second-half display, Wolves could even afford the luxury of a missed penalty as Bakary Sako’s 73rd-minute spot kick hit the top of the bar, while Posh keeper Bobby Olejnik made fine saves to keep out Sako in the first half and Nouha Dicko and Sam Ricketts in the second.
A third club record went Wolves’ way too as the shutout equalled the 23 achieved in 1923-24, to add to their new milestone of nine consecutive wins and most away victories, 14.
Jackett made three changes to the side that drew 0-0 at Stevenage on Tuesday night.
Jack Price, Sako and Dicko replaced James Henry, Liam McAlinden and Leon Clarke.
Sako was back from a toe injury that kept him out of the last two games, while Henry missed out after lasting just 11 minutes in midweek due to a groin problem that is expected to have healed for next Saturday’s trip to Crewe.
Posh, who featured former Wolves right-back Mark Little, kicked off attacking the South Bank and they played a stubborn part in first half shaded by the home side.
For all Wolves’ dominant possession, they created only two openings as Posh’s defence held firm.
The first came in the 14th minute when Dicko was crowded out on the right hand side of the box and Sako steamed in for a fiercely-hit low drive that was palmed away by Olejnik.
The only other real chance of the first period for Wolves came 10 minutes later when Michael Jacobs tried to find the top corner from 25 yards and was inches away with a curling shot.
Posh threatened on 28 when Little put through Conor Washington and the striker rounded keeper Carl Ikeme but was driven wide and could only cross into the box and Wolves held firm.
Wolves had the excellent Richard Stearman to thank for repelling the visitors’ other opening when after Grant McCann’s free kick hit the defensive wall, the former Leicester stopper threw himself in front of Danny Swanson's shot that seemed to be heading for the top corner.
If Wolves struggled to break through Posh’s defence in the first half, they did it in double-quick time at the start of the second after the visitors brought on Lloyd Isgrove for Swanson at half-time.
Batth rose with a towering header from Sam Ricketts’s cross from a short corner taken by Jacobs to break the deadlock.
The defender was booked for lifting up his shirt in celebration with fans.
But the goal seemed to allow Wolves to step up a gear and they created several more chances.
Dicko outpaced the defence before forcing Bobby Olejnik into a fine save to tip away.
The former Villa youth shotstopper then flung himself to his left to keep out Ricketts’s left-foot shot in the 62nd minute after the captain dispossessed Nathaniel Knight-Percival, who replaced Josh Payne on 55, on the touchline and cut inside.
Posh’s first chance came four minutes later when Britt Assombalonga climbed above Scott Golbourne from Tommy Rowe’s deep cross but headed a foot over.
Two minutes later Posh were regretting the miss as Wolves doubled their lead when Edwards bundled home left-footed after Olejnik produced a tremendous save to keep out a vicious free kick from Sako on the left.
Dicko appealed in vain for a penalty on 70 when he ran across Michael Bostwick and fell to the ground.
But two minutes later the same combination worked as Wolves were awarded a spot kick as Dicko fell over Bostwick’s outstretched leg as he went round him.
Sako could only blaze his kick on top of the bar and over though to prevent Wolves going three goals ahead.
It was all Wolves but Ikeme was forced into action in the 81st minute with a fine stop to his left to keep out Bostwick’s drive.
But Wolves had little trouble seeing out the rest of the game as they took another giant step towards promotion.
