Magpies march on the Met Police: Report Maidenhead United 2, Met Police 1
Adrian Clifton's second half header from Danny Green's corner proved decisive as Maidenhead United booked their place in the next round of the FA Trophy at York Road.
The barrel-chested midfielder rose high to nod home Green's 52nd minute set piece to put the hosts 2-0 up and in control of the cup tie.
The visitors briefly threatened a comeback when Dean Bown scored following a howler from United keeper Elvijs Putnins in the 66th minute, but resolute defending from the hosts ensured theirs is the name in the hat for the next round.
United took a 24th minute lead when Bobby Behzadi's cross shot looped over Met Police keeper Stuart Searle and into the net.
Met Police began brightly but the first real chance fell to ex Blackburn Rovers and Blackpool man DJ Campbell whose low shot on the turn was well saved by Searle.
After Behzadi put the Magpies in front Putnins distinguished himself with an excellent low save from Matt Pattison who went clean through minutes later.
Clifton's headed goal in the 52nd minute put United in cruise control but Met Police winger Bradley Hudson-Odoi thumped the post from distance in the 60th minute and Bown took advantage of a clumsy slip from Putnins to roll the ball into an empty net in the 66th minute.
United managed to reassert themselves however, and came close to a third goal when the impressive Sam Barratt's low cross was spilled out to Green, but Searle reacted well to push the midfielder's effort behind for a corner.
