Second-half strikes from Chris Eagles and Gael Kakuta sent Bolton into the fourth round of the Carling Cup as they comfortably beat Aston Villa.
Eagles found the net from 20 yards via a slight deflection off Villa defender James Collins after Marc Albrighton had given away possession.
Gabriel Agbonlahor had Villa's best chance but his tame header went wide.
Debutant Kakuta doubled Bolton's lead with a drilled shot from the edge of the area after Villa failed to clear.
Bolton had the better of the first half and were unlucky not to take the lead when Eagles's corner was met by centre-back David Wheater, whose header thudded against the outside of the post.
Soon after Bolton keeper Adam Bogdan made a crucial near-post stop to block Agbonlahor's shot from Albrighton's dipping centre.
But while the first half was tame, the second saw more action with Eagles giving Bolton the lead after taking advantage of the ball bouncing off Albrighton into his path and he hammered a powerful drive past Shay Given from 20 yards out for his first goal for the club.
And with 12 minutes left Kakuta doubled Bolton's lead when he drilled Ricardo Gardner's floated free-kick into the box past Given.
