Towering striker Matt Smith was Oldham's FA Cup hero once again as his last-gasp equalizer earned the League One strugglers a fifth-round replay with Everton after a 2-2 draw Saturday.
Smith scored twice in the Latics' fourth round triumph over Liverpool but had been sidelined since with a shoulder injury he picked up in that match.
But the 23-year-old Manchester University business management graduate, who Oldham plucked from nonleague obscurity at Solihull Moors, climbed off the bench to head home Jonathan Grounds' corner in the fourth and final frantic minute of stoppage time.
As was the case against Liverpool, Oldham -- playing under caretaker manager Tony Philliskirk -- had its Merseyside opponents reeling when on-loan Reading winger Jordan Obita supplied a 13th-minute lead.
Howard was finally beaten as Smith prospered in a crowded penalty area that featured Latics keeper Dean Bouzanis attacking Grounds' decisive delivery.
Oldham caught Liverpool cold with an early goal in its fourth round triumph but was unable to repeat the trick during a fragmented opening.
Nikica Jelavic, restored to the Everton starting lineup in favor of Kevin Mirallas, had a glimmer of an opening in the eighth minute from Steven Pienaar's through ball, but the Croatia striker was crowded out by Latics center back James Tarkowski as he looked to get a shot away.
The England left back's strike was deflected over and, after Oldham dealt with the resulting set-piece pressure, Boundary Park was sent into raptures.
Lee Croft broke unchallenged from his own half down the Everton left before driving low across goal where Obita's perfectly timed run was rewarded with a tap-in.
The lead remained intact for 11 minutes until Everton successfully took a direct rout to goal. Jagielka's raking long ball was flicked on by Jelavic and Anichebe got the better of Jean-Yves Mvoto to rifle past Bouzanis.
Undeterred, Oldham surged forward in response and, after veteran striker Chris Iwelumo made his presence felt to cause havoc inside the Everton area, Obita thudded a shot against the base of the post.
In the 32nd minute, Jelavic came out on the wrong side of a marginal offside call when he converted Pienaar's defense-splitting pass.
A lucky break would have been welcome for Jelavic and the heavy touch that allowed Bouzanis to mop up further danger shortly before the interval displayed the dwindling confidence of a man with one goal in his past 12 outings.
He had a new partner in attack for the second period as Mirallas replaced hamstring victim Anichebe and the new man would make an instant impact in the 48th minute.
Mirallas' inswinging corner from the left caught out Bouzanis, allowing Jagielka to steal in front and nod into an unguarded net.
Everton was intent on driving home its advantage and some deft interplay between Pienaar and Marouane Fellaini saw the former bring Bouzanis into the action once more.
Another Mirallas corner had Oldham in trouble before the hour, arching past the massed ranks at the near post and narrowly evading Leon Osman.
Philliskirk responded by sending on Oldham's fourth round hero Smith for Iwelumo and club captain Dean Furman in place of James Wesolowski, and the latter visibly sought to rouse his teammates. Baxter responded by smashing a 25-yard half-volley over.
Pienaar ended an enterprising evening's work by slowly making way for Bryan Oviedo and such Everton gamesmanship was justified as Oldham pressed once more, with Tim Howard plunging to his right to superbly deny Smith following a layoff from fellow sub Simpson.
At the other end, Jelavic passed up the opportunity to make the tie safe with eight minutes to play, blazing over from Darron Gibson's fine flighted pass.
In the 89th minute Simpson had a glorious chance to earn a replay as he shrugged off the attentions of Phil Neville to collect Tarkowski's wonderfully-weighted lofted pass, but Howard stopped a shot that lacked purchase before seeing the rebound lashed into the side netting.
Much to Simpson's relief and the locals' delight, Smith would sensationally spare his blushes.
