Loanee Astrit Ajdarevic helped the Bulls beat Bristol Rovers 2-1 in a reserve match.
The Pirates scored first from a corner taken by former Bulls trialist Ryan Burge, but Ajdarevic scored from the spot shortly after with a deflected effort late on securing the win.
The official Bulls site credits the second goal to an unnamed trialist but the Pirates site named Aidan Thomas, a striker for the youth team, as the scorer.
