Nathaniel Mendez-Laing and Conor Hourihane scored as Derby extended their unbeaten run in all competitions to 18 games with a 2-1 win over League One play-off rivals Bolton.
Wanderers had conceded only once in eight outings before Mendez-Laing set the fourth-placed Rams on the way to a fifth straight win after 16 minutes.
Defender Will Aimson was initially credited with turning Tom Barkhuizen's right wing cross into his own net, but Mendez-Laing's sixth goal of the season, and first in 2023, was later confirmed.
More than 30,000 watched the third tier's match of the day, and the home crowd celebrated a second goal 18 minutes from time.
Bolton have never won at Pride Park or achieved an away win over the Rams since 1981, and they were unable to avoid a first defeat in nine games despite substitute Kieran Sadlier's stoppage-time consolation.
Goal! Derby County 2, Bolton Wanderers 1. Kieran Sadlier right footed shot from the centre of the box to the bottom right corner. Assisted by Dion Charles.
