Carshalton Athletic joined Lewes in confirming promotion from the Bostik League South on Saturday.
The Robins edged out Whyteleafe by the odd goal in five at the War Memorial Sports Ground to assure themselves of a place back in the Premier – and now it’s a shoot-out with the Rooks for the title.
In front of a crowd of 588, `Leafe led through former Robin John Scarborough after 24 minutes, but Tommy Bradford equalised 3 minutes after the break, only for Scarborough to net his second on the hour-mark.
It didn`t look good for the hosts when Bola Nkori-Venceslas added a third for `Leafe just 2 minutes later.
But the party wasn`t going to be spoiled as a quickfire brace from Ola Sogbanmu and then a second for Bradford in stoppage time won it for the Robins.
Lewes maintained their two-point advantage at the top after a 2-0 Dripping Pan win over East Grinstead Town, thanks to Jonte Smith after 47 minutes and Marcus Elliott 15 minutes from time in front of 659, but Carshalton have a game in hand.
There was one other situation finally settled on Saturday and that was Shoreham being put out of their misery and being confirmed as finishing bottom after they lost 1-0 at the Pilot Field to Hastings United, Sam Adams` 83rd minute goal proving decisive.
The remaining top six spots are now occupied by Cray Wanderers, Greenwich Borough, Corinthian-Casuals and Hythe Town, with Walton Casuals still just about in the mix in seventh.
Cray hammered South Park 8-0 at Bromley with Brandon Scott and Charlie Macdonald both bagging braces, Lea Dawson, Aaron Rhule, Jay Leader and Junior Dadson singles.
Greenwich were 2-1 winners at the Homelands against Ashford United, with a Jack Barham double in 4 minutes midway through the first half being enough, despite Josh Oyinsan`s 52nd minute reply.
Corinthian-Casuals could only draw at Southwood against Ramsgate after leading 2-0 with Max Oldham and Harry Ottaway goals in the first half.
Aaron Millbank`s penalty on 56 minutes and then sub Rory Smith 9 minutes from time earned the Kent hosts a point.
Hythe won 5-2 at Reachfields against Chipstead, taking a 4th minute lead through Zak Ansah before being pegged back by Eddie D`Sane just before the break.
Two goals in 2 minutes just after the break from a Matt Warren own goal and Liam King gave the Cannons the lead that Kieron Campbell added to on 69 minutes.
D`Sane`s second reduced the arrears 3 minutes later, only for sub Jerson Dos Santos to make it 5-2 on 77 minutes, and although Dean Lodge pulled a third back 7 minutes from time, Hythe had done enough.
Walton Casuals` hopes probably went with a 2-1 defeat at Princes Park by Thamesmead Town as they trail Hythe by five points with three games to go.
Josh Kelly gave them a 12th minute lead but Joe Denny after an hour and Laurent Mendy 17 minutes from time turned it in Mead`s favour.
Elsewhere, David Smith`s 81st minute effort proved enough for Sittingbourne at Phoenix Sports, while Faversham Town won 3-0 at Horsham, who had Shane Cojocarel dismissed in the 67th minute but by then his side already trailed to goals from Luke Harvey in the 13th and 53rd minutes – Mo Dawodu adding a third on 73 minutes.
Guernsey FC maintained their decent end to the season with another away win, this time 3-1 at The Altira Park Stadium against Herne Bay with Tom De La Mare, Paris Pereira and Dave Rihoy outgunning Jake Embery.
Molesey and VCD Athletic shared a 1-1 draw in the day`s other game in which the visitors led through Alfie Cue`s 62nd minute goal until a minute from time when sub Benga Ogunseye grabbed the hosts` equaliser.
