Beaconsfield were denied a deserved share of the spoils when a scrambled goal in time added on gave all three points to visitors Aylesbury United.
With three players making their debut in defence - and well marshalled by Guri Demuria - The Rams started strongly, enjoying decent periods of possession though in truth, with little end product. Jack McKnight had a header well saved by Zaki Oualah on ten minutes and ten minutes after that a last ditch block prevented The Rams going ahead following a bout of ping pong in The Ducks box.
McKnight saw a quality free kick met with an equally fine save by Oualah on 25 minutes whilst Aylesbury's first meaningful effort didn't arrive until the 40th minute when Lea Coulter sent a shot wide.
The second period began with Ollie McCoy going inches wide on 47 minutes - 120 seconds later The Ducks made The Rams pay when Jordan Frederick made the most of the defences failure to clear their lines to send a decent shot across Sam Bunting.
Aylesbury then enjoyed a good period of dominance and Bunting had to be at his best to keep out good efforts in the 50th and 70th minutes. The failure of United to add to their goal whilst on top gave Beaconsfield a glimmer of hope and on 76 minutes a good run and cross by Spencer Maw saw the ball land at Jack McKnight's feet and he slotted home albeit with a strong deflection from a Ducks defender.
McKnight then went narrowly close to giving Beaconsfield the lead on 80 minutes whilst a decent cross by Maw five minutes later failed to get a strong enough connection to force a winner. That honour went to United as a cheaply conceded 92 minute free kick on the right was sent into The Rams box and fell kindly to Ryan Kinnane to poke home. Delight for The Ducks, despair for The Rams.
