Sunderland were hit by a late blow as their good work was undone in the first half at Wigan, with the scores tied at 1-1 at the break,
The visitors almost made the breakthrough after 10 minutes when Bailey Wright's header from Aiden McGeady's corner was turned away, with good work from Jack Diamond initially to win the flag-kick.
McGeady then saw a 25-yard shot from a short free-kick tipped wide as the Black Cats pressed for the opener.
Sunderland got the goal their pressure had deserved when Charlie Wyke volleyed home McGeady's perfect cross at the far post.
However, the lead didn't last long, and Wigan were level when poor defending allowed Dodoo time to turn a corner back across goal, where Will Keane was able to rifle home from close range.
