It's advantage Marlow United in the race for the Thames Valley Premier Division title, after they beat Burghfield 2-0 on Saturday and Cookham Dean slipped to an unexpected 4-1 defeat to Woodcote Stoke Row.
League leaders Dean took the lead through Nathan Lishman but suffered their first league defeat since September 15 with Ryan Corbett heading home unmarked to equalise for Woodcote before three late goals - two of them for James Griffiths - handed their rivals the points.
Defeat opened the door for Marlow United, and the Flying Blues capitalised with a routine victory.
They now sit just three points behind Dean with two matches in hand and their superior goal difference means they'll all but wrap up the title with victory at Burghfield on Saturday.
They then round off their campaign at home to Woodley United Royals on Tuesday night.
Burghfield made them work hard for the points on Saturday.
After a goalless first half the Flying Blues netted their first after a mazy run and finish from Liam Bushay, the striker scoring at the second attempt after the keeper saved his original shot.
They then doubled their lead 20 minutes later through Felix Prudden.
The forward rattled the crossbar but had the presence of mind to nod home the rebound.
