I had this down as a 3-0 defeat in the Badger League, so 2-0 is a little more respectable. Charlton remain in 11th place.
It was a comfortable victory for the Rams over Charlton at Pride Park. A David McGoldrick penalty and a header from central defender Eiran Cashin ensured the Rams remained unbeaten at home in the league since early October.
Charlton's bid for a fourth consecutive away league win suffered a setback when they conceded in the ninth minute.
Conor Hourihane's shot was handled by Michael Hector and McGoldrick coolly dispatched the spot-kick.
Rams goalkeeper Joe Wildsmith did well to close down Jesurun Rak-Sakyi, but Derby threatened whenever they went forward and Hourihane had a low shot saved by Ashley Maynard-Brewer in the 33rd minute.
McGoldrick was denied a second in first half stoppage time when Maynard-Brewer made a good save low to his right and Wildsmith had to react sharply to keep out a Scott Fraser drive in the 49th minute.
But Derby gave themselves breathing space in the 69th minute when Hourihane's free-kick from wide on the left was headed in by Cashin from eight yards.
Louis Mendez commented: 'Derby are top six material and we're not. We can look okay against Exeter and whoever, but look that little bit outclassed against the big boys.'
Dean Holden was frustrated by the number of unforced errors in the game: https://londonnewsonline.co.uk/dean-holden-bemused-by-amount-of-unforced-errors-during-charltons-defeat-at-derby-county/
Louis Mendez says that Charlton face another season in which there is nothing left to play for. Macaulay Bonne needs to provide more, although it is not all his fault as he lacks service: https://londonnewsonline.co.uk/four-takeaways-from-charltons-2-0-loss-at-derby-county-rams-rarely-out-of-second-gear-but-had-more-than-enough/
