Ali Al Habsi
Saved well from Jerome early on and went one better in the second period with stops from Puncheon and Gayle. Got Wigan's passing game going with some early distribution and always providing an option for his team-mates.
Like his defensive accomplice, it was a commanding display from the centre-back. Showed good awareness to track the elusive Jerome and Puncheon when they came inside and was dominant in the air.
Showed precious little attacking intent in support of McManaman but it hardly mattered and carried out his primary role without inviting Palace onto the hosts.
Hardly put a foot wrong in shackling Chamakh and formed an impenetrable partnership alongside Barnett for the majority of the contest to prove Ivan Ramis will barely be missed if he leaves the club.
Was guilty of a few positional lapses but that aside, the Chilean was responsible in helping quell the dynamic Puncheon, who rarely got involved. His forward bursts helped McClean terrorise his marker.
Took his goal superbly against his former employers by opening his body and stroking the ball home and played the anchor role superbly, keeping things ticking along without being overly-intricate with his passing.
Did brilliantly to tee up Watson for the opener before scoring the winner after a great run. Probed against Mariappa throughout with a series of jinxing runs but, importantly, his end product was decisive on most occasions.
Tidy but also very effective in winning back possession and giving it to the likes of McClean and McManaman to wreak havoc further upfield.
Excellent performance from the returning winger, who gave Parr a torrid time before going off injured. Constantly looked to get at the full-back by utilising his searing pace and always sought to exploit the pockets of space he found.
Despite his lovely touch in the build-up to the opening goal, his overall contribution was poor. Constantly outmuscled and gave possession away too cheaply in dangerous areas early on but, to his credit, did improve to help set up a famous win.
Largely ineffective as the lone spearhead to the Latics attack but battled tirelessly to prevent Palace's defenders and midfielders to enjoy time and space. The first line of defence strategy helped liberate the likes of Watson to break forward.
Made some solid stops but could do little to prevent Watson or McClean from netting. His kicking was consistent throughout and so was his ability to claim the ball at set pieces.
His contribution to the match will largely be remembered for a sickening injury after coming off worse in a clash of heads with McManaman, who had run him ragged early on.
Returned to skipper the side and headed everything back that the Latics launched at Palace aerially but looked slow across the ground for Watson's goal.
Given a torrid afternoon by McClean's attacking forays and offered the struggling Puncheon no assistance down the right in fear of leaving space in behind. McClean cashed in to set up and score after escaping the makeshift right-back.
Showed intent to come out from the back and push Palace forward and dealt well on the whole with the ineffective Maynard.
Just could not get going. Failed to beat Beausejour for the entirety of the afternoon and his passing was inconsistent to say the least. With that said, he was desperately unlucky to see Al-Habsi claw his volleyed strike away.
Composed figure on the ball, spraying passes around but there were very few that got his side going forward but hardly put a foot wrong all afternoon.
Needs to stop the Hollywood passing to fulfil his promise but his delivery from set pieces was a highlight, evidenced by his assist for Wilbraham's goal, in an otherwise peripheral display.
Completely over-run by Wigan's midfield triumvirate. Did not offer enough support in either half of the field but relished the battle and at least got stuck in to his opponents.
Showed some impressive hold-up play on occasions but his contributions were sporadic when his side needed more of an outlet to find in attacking areas.
Woeful outing from the Moroccan, who gave the ball away frequently and never looked like scoring during his time on the pitch. Not a surprise to see him sacrificed as Palace sought an equaliser, which they duly got.
Did not have enough time to make a sufficient impact on the game.
Wasted a presentable opening after coming on by lashing wide but helped shore up the midfield as well as breaking to give the Latics something to hit on the counter.
Barely involved during his stay on the pitch, failing to get the better of either central defender as Wigan looked to close out the win.
Struggled to get up in support as he was pegged back by the dangerous McManaman. Could not handle the winger at times but stuck to his task.
Emerged from the bench as part of a double substitution midway through the second half and injected some much-needed pace and verve into the Palace attack. Came close with a searing effort which was pawed away by Al-Habsi.
The second part of the substitution and it was his clinical finish from Bannan's corner - his first touch - that hauled his side level.
