Two goals from Luke Zona were enough to see Ashbourne Aztecs under-10s reach the quarter-finals of the cup in a hard-fought but deserved victory against spirited league leaders Chesapeake.
Aztecs started very strongly, with Adam Leigh and Charlie Land attacking down the flanks and forcing a flurry of corners in the first five minutes.
Zona saw two shots saved, followed by a drive from Land that went just over the bar as the Aztecs continued to press.
When Chesapeake did manage to get forward, Josh Lee and Toby Ainsworth were strong in defence, with both players on top of their game.
Lee headed clear on more than one occasion and even got an accidental kick in the face for his troubles, whilst man-of-the-match Ainsworth passed out of defence with a very cool head.
James Donlan and Zona dominated the middle of the park and combined well just before the break as Donlan beat a player before sliding a through ball inside the defender for Zona to latch onto, but the keeper made an excellent save.
Debutant Jonathan Dawkins instantly showed trickery on the wing and delivered some telling crosses.
The start of the second half saw Chesapeake come more into the game but George Martin tackled like a demon with typically strong and well timed challenges.
Whenever the ball did breach the defence, Ben Johnson in goal was equal to everything thrown at him and confidently dealt with all shots.
Land made a great run, virtually the length of the pitch and found Zona, whose shot was again well saved.
Lee then smashed a screamer that flashed just wide.
Leigh and Ainsworth came back on and the pressure was unrelenting but extra time and the dreaded penalties were looming large until Aztecs finally broke the deadlock.
Lee played the ball out of defence to Zona, who moved it on to Land, who then raced down the wing, and when his shot could only be parried by the keeper, Zona was on hand to poach the opening goal.
There was still time for Donlan to show his silky skills and he was nearly rewarded with a goal as his strike from distance was flying into the top corner until the keeper made a great save.
The game was made safe two minutes from time as that boy Zona beat two men and ran half the length of the pitch before slotting home.
