Conor McAleny was on target twice as Latics scored four goals to register an emphatic Bank Holiday win at Crawley Town.
McAleny struck in either half as Keith Curle’s side turned on the style to claim the points in comprehensive fashion at Broadfield Stadium.
The four goals were reward for an authoritative all-round performance which saw Latics dominate throughout as they bossed possession, created countless chances and oozed confidence all over the pitch.
Having controlled the first half from the off, gradually getting closer to an opening goal, the visitors scored twice in as many minutes just before the break through McAleny and Cameron Borthwick-Jackson.
Back among the goals, McAleny was on target again three minutes after half-time and despite conceding a late goal, there was still time for Dylan Bahamboula to mark his return from international duty with Congo by scoring a stoppage-time strike.
Latics’ intentions were clear from the outset, McAleny’s early shot charged down by Joe McNerney and that set the tone for what was to follow.
Glenn Morris saved from both Callum Whelan and Bahamboula before the Crawley goalkeeper had to be alert to make a fine double-save to deny Whelan and Davis Keillor-Dunn in quick succession.
Midway through the half, Alfie McCalmont lifted an effort over after another quick Latics break, this time involving good work from Keillor-Dunn on the right.
Harry Clarke directed a header wide before McAleny went close with another effort as Latics continued to press forward and move the ball quickly.
At that stage, the only question was whether Curle’s side would make the breakthrough before half-time.
Five minutes before the interval, they did just that, Keillor-Dunn playing a magnificent through-ball to pick out the run of McAleny, who applied an assured finish.
And no sooner had they found a way through than Latics had two, Borthwick-Jackson netting his first league goal in Oldham colours with a fine angled finish after cutting in from the left.
Clearly buoyed by their bright football and deserved goals, the visitors came out for the second period with the same intent and they were soon celebrating again.
This time McAleny broke into the Crawley area and exploited the space afforded to him by sliding a low finish past Morris.
There was to be no let-up from Latics as they continued on the front foot, Keillor-Dunn and Whelan both going close before Borthwick-Jackson sent an angled shot past the far post.
Bahamboula’s low free-kick was claimed by Morris and the Congo international displayed tremendous footwork to engineer a chance for McAleny to send the ball wide.
Laurie Walker made an excellent finger-tip save to touch over Jack Powell’s curling free-kick. From the resulting corner, James Tilley pulled a late goal back for Crawley, but Latics had the final say.
After an initial effort from Nicky Adams was blocked by Morris, Bahamboula turned the ball home from close range, marking his return to the side in style and crowning an excellent all-round team performance.
