New signing Josef Bursik was handed an immediate call to action as he started in the strongest line-up named so far by boss Darren Moore.
And he found himself up against England’s record goalscorer Wayne Rooney who was featuring for Phillip Cocu’s Rams in their second pre-season outing.
Moore named two midfield trialists in his starting XI and added two from the bench in the second half.
Reece James - who suffered an injury in training at the start of the week - and Jon Taylor were both absent for Rovers.
The Rovers boss had called for a step-up in performance from his side after being pleased with their run outs in wins over Scunthorpe and Bradford.
With their first competitive fixture now just a week away as they visit Blackburn Rovers in the Carabao Cup, Moore and his squad are fast running out of preparation time.
Derby hit the post through Craig Forsyth while Rovers went closest with Ben Whiteman firing over the bar and Jason Lokilo pulling a shot wide.
Whiteman forced a save from Derby keeper Kelle Roos after the break while Curtis Davies headed narrowly wide from a free kick in the late stages.
Rovers: Bursik (Jones); Halliday, Wright, Anderson (Horton), Amos (Trialist); Whiteman (Hasani), Trialist; Lokilo (Trialist), Coppinger (Gomes), Trialist; Okenabirhie (Trialist).
Derby (first half): Marshall, Wisdom, te Wieri, Forsyth, Buchanan, Bird, Rooney, Bennett, Whittaker, Knight, Marriott.
Derby (second half): Roos, Bateman, Davies, Solomon, Lowe, Evans, Shinnie, Shonibare, Ibrahim, Jozefzoon, Hector-Ingram.
