  This paper compares the divisorial gonality of a finite graph $G$ to the
divisorial gonality of the associated metric graph $\Gamma(G,\mathbb{1})$ with
unit lengths. We show that $\text{dgon}(\Gamma(G,\mathbb{1}))$ is equal to the
minimal divisorial gonality of all regular subdivisions of $G$, and we provide
a class of graphs for which this number is strictly smaller than the divisorial
gonality of $G$. This settles a conjecture of M. Baker in the negative.
