No doubt the Spaniard would have hoped for his backline to remain secure early on, but he was forced to save from Routledge two minutes in after an Espinoza error. The Spaniard made a mistake of his own soon enough as he picked up a back pass, but generally he did well between the posts, and he could do little to prevent any of the goals.
The Wigan captain returned to the team and had mixed evening. In the first half he looked comfortable, but in the second he found things more difficult as Swansea posed a threat going forward. He did, however, produce a wonderful defence-splitting pass to set McCarthy up in the second half.
Usually up and down the flank for the full match, Boyce's role seemed significantly more disciplined on Tuesday, perhaps in keeping with Wigan's treacherous position in the table. Early on he produced a couple of clumsy passes and that was a sign of things to come as he rarely looked at ease.
Deployed as the destroyer in midfield, Watson's work rate was notable as he marched all over the pitch, hassling opponents whenever he could. Sometimes his reliance on brute force meant he completely missed the ball, but he never let Swansea's men settle in possession.
Reportedly a potential target for a number of the Premier League's more illustrious clubs, and it is understandable. Although not particularly flashy, the Irish midfielder kept the ball moving and his passing was accurate as the majority of Wigan's attacks went through him. Fittingly he scored Wigan's second with a good finish, but ultimately that goal proved meaningless.
The least impressive of Wigan's midfield if truth be told. His long-range passing was fairly poor and he did not offer much in the final third, but he did his job to a satisfactory standard as he pressurised the visitors' midfield and passed to the more creative influences, but made a crucial error for Swansea's third goal as he missed a header.
Scharner had a straightforward first half, but in the second half he, like the rest of Wigan's defence, was all over the place. His choice to play a simple pass rather than get the ball forward in the first half was met by jeers from the home fans, to which Scharner responded by putting a finger to his lips. They were not impressed by that, either.
Making only his fourth Premier League start for Wigan, Espinoza got off to a nervous start as he gifted Routledge a chance on goal. Joel bailed him out on that occassion, but he frustrated in attack due to his erratic crossing. However, he opened the scoring with an excellent volley just before half-time.
The Ivorian saw plenty of the ball and he proved a useful target as he held the ball up brilliantly. His shooting was accurate, but he struggled to get into great positions in the area, while Vorm kept him out on numerous occasions.
Since the turn of the year, McManaman has been impressive for Wigan and he certainly had his moments against Swansea, too. He showed off a plethora of tricks against Ben Davies, giving the left-back a real battle. His influence dried up a little as the match went on and he was replaced by Di Santo on the hour mark.
The Netherlands international looked shaky all evening. He was lucky not to concede an indirect free kick before making several nervous saves and punching straight to Espinoza for the opening goal. He clashed with team-mate Ben Davies late on and had to be taken off on a stretcher, with what looked to be a serious injury.
Never shyed out of making a tackle, and he produced several strong challenges that were generally well-timed. Moved out wide to counter Maloney in the second half, and he did so to great effect, while he scored Swansea's third after capitalising on some truly disastrous Wigan defending.
The first 20 minutes of the match would have felt like an awful lot longer for the left-back as McManaman tried every piece of skill he knew against him. After that early worry, however, Davies stood up well to the challenge, nullifying the forward's threat.
Making only his 10th Premier League start of the season, club captain Monk could do little to stop Wigan in attack. He won a few headers, but his presence appeared to hinder Vorm for the hosts' first goal.
Did not have a particularly tough evening against Espinoza, but he allowed the Honduran to cross on way too many occasions. The Wigan man rarely tried to beat Rangel, but he was given too much space. Scoring Swansea's first equaliser with a well-finished volley made up for that, though.
Chased Kone around for the whole match, and he did not have much success in that respect. He kept the former Sevilla man from dribbling into the danger area, but he struggled to tackle him or prevent him from offloading to team-mates. He also hammered an indirect free kick over from eight yards out.
J. de Guzmán
Along with Britton, the man on loan from Villarreal allowed Wigan to control possession too much in the first half, but he was vastly improved after the break as he tackled well and broke forward from midfield with gusto.
Struggled to create space and he was not given an awful lot of time on the ball by Kone, but he remained calm in all cases. Asserted himself more after half-time as Swansea became more inclined to attack, but he spent most of the match sitting deep.
The Spaniard was virtually anonymous in the first half as Wigan did all the attacking. In the second period he was a little more lively, but he was still quieter than he would have liked even though Swansea were clearly more willing to attack.
Like most of his team-mates, Routledge was relatively muted in the first period. He had one early chance which Joel saved before proving more influential after half-time. Caused plenty of problems when he cut in from the left and played a role in Tiendalli's goal.
Before Tuesday, the Israeli striker had gone 29 matches without scoring, a run which dated back to October 2011. However, after good movement he tied the Wigan defence in a knot and found the net via a Boyce deflection. Aside from the goal he was quiet and was eventually replaced by Dyer.
With Wigan's defence capitulating, Martinez brought Stam on to balance their backline. However, he did not last long as an injury forced him off, thus leaving the hosts with 10 men.
Martinez threw men on in a desperate bid to rescue a point, but Gomez had little impact, with his most notable action being a foul on Davies.
F. Di Santo
The Argentine added an extra body to the Wigan attack, but his attempts to create were not fruitful as he either crossed into the first man or failed to pick out a telling pass.
