For the second home game in a row, an Oldham side that was full of verve, energy and self-belief kept opponents scoreless in the second half when beating Halifax Panthers 16-12 at Bower Fold.
In their last home game they scored 18 unanswered points after half-time to beat Swinton Lions 28-20.
This time, they trailed Fax 12-4 at the interval, but stormed back down the slope to win 16-12 with a winning try four minutes from the end by on-loan centre Jack Croft, goaled beautifully from wide out by full-back Callum Green, who had a blinder.
Winger Tommy Brierley and sub forward Martyn Reilly also scored tries, with Green landing two goals from three attempts.
A goal in the first five minutes and another one six minutes from time were enough to see Ashton safely into the second qualifying round of this year's FA Cup and a home tie against Scarborough.
After squandering a two-goal lead at home to Prescot Cables on Saturday, Hyde United spared their FA Cup blushes with a 1-0 win in Tuesday’s First Qualifying Round replay.
