Promoted side Bochum were playing their first home game in the Bundesliga in more than a decade on 21 August last year, and Holtmann evidently decided the occasion merited something special.
Receiving possession on the left-hand side of the pitch and just inside Mainz's half, the 26-year-old began a Lionel Messi-esque run, dribbling past five defenders and into the box before slotting the ball into the net for the opening goal on 21 minutes, paving the way for an eventual 2-0 win.
"As soon as I'm in the final third I always try to get a shot away," Holtmann told bundesliga.com afterwards. "But I then thought that I needed to keep going because my first touch wasn't good. Obviously the fact that it then led to a goal makes me incredibly happy."
