Harry Kewell's side continued their preparations with two hour-long games to increase fitness as well as test further trialists.
Held at Curzon's Tameside Stadium, on a sunny evening, Oldham fielded two different sides once more.
The first being what would resemble a starting XI, including two trialists in the centre of midfield again.
With the second featuring five trialists and two academy second-year scholars.
Game One: Curzon 0-2 Latics
The hosts started on the front foot but as both teams found their footing, it was Latics that began to increase the pressure on the Curzon goal.
Half-chances came and went, with the likes of Grant and Rowe shooting off target.
As the slick attacking movements between the front four continued it was the latest signing McAleny that broke the deadlock on the half-hour mark.
A neat move culminated in Keillor-Dunn hitting a pass into the path of McAleny who skipped past two players before turning on the edge of the box quickly, firing it into the bottom left-hand corner.
After a short break at 45 minutes, Kewell's side continued to dominate with the next goal coming through the increasingly impressive bright spark, Keillor-Dunn to record two goals in pre-season in as many games.
Academy scholar and striker Luamba won the ball in the final third after a misplaced pass from the Curzon defence, allowing the young player to set the Sunderland-born winger free in the area to slot the ball across the goal, past the keeper.
Game Two: Curzon 2-1 Latics
With a host of changes from both sides for the next game on the slick Tameside surface, it was the hosts who got the upper hand during the key moments of the encounter.
Their first goal came midway through as a corner from the left was unchallenged and duly headed in by a Trialist for the Nash.
Dearnley continued to cause problems though, using his pace and technique to carve open opportunities and send defenders chasing him down both channels.
But Curzon doubled their lead through Tharme. A free-kick conceded on the near side meant a looped ball was played into the danger area for the young defender to put his head where its hurts and ultimately be rewarded for his bravery.
As the sun set and the encounter began to come to an end, the final bit of action went Oldham's way as the Trialist playing at left-back found the ball land into his path.
Without hesitation on the edge of the box, he hit it sweetly into the goal with his powerful left foot, giving the keeper no time to react, with the last kick of the game.
On the whole the test was worthwhile and time well spent for most importantly fitness, as pre-season now goes up another level in terms of intensity and competitiveness.
With fixtures for the 2020/21 season starting to be confirmed and a couple of pre-season fixtures left against higher league opponent, the next few weeks will prove pivotal before the real action returns after a lengthy wait.
