The winless and pointless home side, did put in a strong showing initially and, on 27 minutes of play, took the lead with a converted score.
However, Leamington were soon on equal terms when Craig Smith claimed lineout ball, which Centre, Rich McKowen, used to force his way through, for his side’s first try of the afternoon, which was converted by James Dunne.
From the restart, Leamington added another with a fine individual try from Josh Jones.
Leamington had the perfect start to the second period, when Miller, once again, fielded a high clearance kick and set McKowen away for a perfectly crafted try. Dunne then obliged with the conversion.
The home side were now struggling to keep pace with the game and fell further behind to two consecutive tries, from winger, Conor Chamberlain, both converted by the boot of Dunne.
Replacement, Jimmy Creith, had an immediate impact on the game, setting up the ball in midfield, which Leamington skipper, Joe Kinghorn, latched on to and out run the home defence for another well-worked try, duly converted by Dunne.
The Leamington backline were working very hard to use the good ball, provided by the Pack and Half-Backs, Sam Russell and Louis Vaughan had linked well all afternoon to facilitate this provision.
Winger, Kofi Miller, who had set up earlier scores for his team, then got on the scoresheet, following a mesmeric run down the far-side flank, which the Earlsdon defence failed to stop.
With seven tries already bagged, Leamington were still pressing and a slick inside pass from McKowen to Josh Jones, opened up a gap, for the latter to exploit and race down the pitch for another well-engineered score.
Dunne was on target once again with the conversion, bringing his points tally to 14 for the afternoon.
The Leamington Pack, who had fought off early pressure from the home side, closed the scoring with a pushover try, claimed by Gareth Shuttleworth.
Leamington return to league duty on the 14th October at Manor Park, kick-off 3.00pm.
