The Black Cats squandered a two-goal lead at Fleetwood in their last league match, but claimed all three points here courtesy of Carl Winchester’s first-half finish.
It was the Northern Irishman’s third league goal of the season, as he converted Dennis Cirkin's low cross in the 17th minute.
The Black Cats had chances to double their advantage but were also forced to withstand some late pressure from Wanderers in the second half.
It’s a result which keeps Sunderland in second place in the League One table, behind Wigan Athletic on goal difference, ahead of Tuesday’s home game against Cheltenham.
Our chief SAFC writer Phil Smith has delivered his verdict on how each Black Cats player fared against Bolton.
