Britt Assombalonga netted the only goal of the game as Daggers bowed out of the Johnstone’s Paint Trophy in the area quarter-final stage at the expense of League One highfliers Peterborough United.
After a goalless opening period, Assombalonga was left unmarked in the box to tap home from Nathaniel Mendez-Laing’s ball in from the byline.
And though the Daggers tried to get back into the game, they again were unable to threaten Bobby Olejnik in the Posh goal.
Manager Wayne Burnett used the opportunity to make four changes from the 3-0 FA Cup defeat at Bristol City as Luke Wilkinson
Ilesanmi, Afolabi Obafemi
and Chris Dickson getting the chance to impress.
After a cagey opening few exchanges, the Daggers had the first opportunity of the game as Dickson managed to slip he slipped his man and was through on goal but his shot was straight at Posh goalkeeper Bobby Olejnik.
After a slow start, Peterborough worked their way into the game and Hogan Ephraim’s shot was cleared off the line by Gavin Hoyte
as the hosts began to up the tempo.
The Daggers did settle down and the game went through a quiet spell, though Mark Little did drill an effort wide 10 minutes before the break when free at the back post, before Grant McCann shot straight at Lewington from 20 yards out.
And the final act of the half was the closest either side came to an opener when Grant McCann curled a free-kick on to the bar.
After the break Dickson almost fired the visitors in front when he chased down an Olejnik clearance and after striking the forward, the ball fell into the side netting.
Pinball ensued in the other box as Daggers failed to clear their lines from a Posh corner and the hosts broke the deadlock on 57 minutes.
Nathaniel Mendez-Laing showed Ilesanmi a clean pair of heels before crossing for an unmarked Assombalonga who had the simple task of slotting into the net.
Mendez-Laing went close two minutes later after another barraging run down the right, but Lewington was equal to the effort.
Daggers did mount some pressure going forward after the Posh goal but for the second game in succession failed to really create anything going forward.
Burnett tried to change things with the introduction of Josh Scott
, but the hosts were able to see out the closing stages to book their place in the area semi-final.
