Derby have continued their good start to the season, easing past visitors Millwall 3-0 at Pride Park.
Craig Bryson put the home side ahead after 24 minutes, passing the ball home after Ben Davies had his shot blocked.
Derby doubled their lead before half-time when Davies again set up Irish Under-21s internationa Jeff Hendrick, who slotted in from 12 yards.
The game was put to bed 20 minutes into the second period when Rams top scorer Steven Davies finished off a passing move.
The Rams move up to third, level with Middlesbrough in second and one point behind table-toppers Southampton while Millwall slip three places to 19th.
