Manager Harry Redknapp was without injured duo Gareth Bale and William Gallas for Saturday's Premier League clash but he must have been concerned that they carried little attacking threat.
In fact, Wigan could have sealed victory three minutes from time but substitute Connor Sammon fluffed his lines.
Whether that miss will prove crucial remains to be seen but Roberto Martinez's struggling side now have the daunting task of three games on the road.
They looked neat and tidy but again their lack of a cutting edge let them down.
After just five minutes Tom Cleverley swung in a cross only for goalkeeper Heurelho Gomes to get there a fraction ahead of Hugo Rodallega.
Spurs were taking time to get into their stride and Luka Modric took matters into his own hands in the 15th minute.
The playmaker burst forward and fired in a shot only to see it blocked by James McCarthy.
Back came Wigan and Maynor Figueroa delivered a fine ball into the area in the 20th minute but Rodallega just failed to get a vital touch.
A minute later Roman Pavlyuchenko made an unsuccessful appeal for a penalty after a challenge by McCarthy - the ball seemed to be outside the area anyway.
This was a better spell by Tottenham and Jermaine Jenas rattled in a shot that was taken by Ali Al Habsi.
Wigan stepped up the pace and Victor Moses twice got into good positions in quick succession but failed to test Gomes.
He got on the end of a corner from Ben Watson in the 27th minute only to a curl a shot over the top.
Two minutes later Charles N'Zogbia laid the ball back to Moses, but his effort was again too high.
Moses then had an appeal for a penalty dismissed by referee Andre Marriner after appearing to have his legs clipped by Benoit Assou-Ekotto.
Wigan were then pegged back only for Al Habsi to make a comfortable block from Rafael van der Vaart.
The hosts started the second half on the front foot and Gomes did well to palm away a cross from Moses in the 49th minute. The ball broke to Rodallega but Michael Dawson blocked his effort.
Six minutes later Gomes again had to be alert to turn away Cleverley's shot from an acute angle after N'Zogbia had supplied the opening.
Redknapp decided to shake things up in the 57th minute with Peter Crouch replacing the ineffective Jermain Defoe.
The visitors were still not posing much of a threat and Redknapp looked increasingly concerned.
Crouch was quickly into the action and found space on the edge of the area in the 65th minute only to send his effort high over the bar.
Moses came off in the 66th minute and was replaced by former Kilmarnock striker Sammon.
Tottenham were beginning to step up a gear and Crouch cleared the bar with a header in the 75th minute with Sandro supplying the delivery.
With Aaron Lennon on for Van der Vaart, the visitors were looking more lively and this was a difficult test for Wigan.
However, they should have clinched victory with three minutes to go when substitute Mohamed Diame released Sammon but he directed his shot straight at Gomes.
