Dover Athletic suffered the second defeat of their pre-season campaign after losing 3-0 against Greenwich Borough at Crabble on Tuesday.
The Southern Counties East League side led 2-0 at half-time before wrapping up the win with a 60th minute penalty.
The game started 45 minutes later than the scheduled 7.30pm start due to delayed arrival of the visitors due to traffic.
But they showed no affects of a limited warm-up by opening the scoring with their first attack in the seventh minute after Michael Power beat Whites goalkeeper Andy Rafferty from inside the six-yard box.
Rafferty was left exposed again seven minutes later when Mohamed Elsa was put clear and he calmly slotted home.
Rafferty then saved twice to prevent Greenwich, whose line-up included former Millwall striker Gary Alexander and Dartford midfielder Peter Sweeney, from increasing their advantage before Chris Kinnear Jnr went agonisingly close to reducing the deficit seconds before half-time.
The midfielder got on the end of Ricky Modeste's cross but his header bounced up and over the bar.
Whites boss Chris Kinnear made three changes at the break with Ricky Miller, Richard Orlu and Duane Ofori-Acheampong coming on for captain Jamie Grimes, Stefan Payne and trialist Julian Wade.
The lively Miller wasted little time in getting involved, firing just wide seven minutes after coming on.
Five minutes later Miller went over in the penalty box after an impressive run but the appeal was waved away,
Another trialist, Antonious Lazarou, then headed a Modeste free-kick over before Greenwich made it 3-0 seconds later from the penalty spot after Rafferty was ruled to have tripped someone.
Jessie Darko made no mistake from the spot, despite a valiant Rafferty guessing the right way.
Kinnear Jnr hobbled off seconds later after making a tackle earlier and was replaced by Liam Bellamy.
Miller, who had scored in each of his previous three games, kept trying to extend that statistic, twice seeing shots saved.
Modeste had a penalty appeal turned down before Lazarou and Orlu both headed over.
Whites host Gillingham on Saturday (3pm).
