  Given a coarse space $(X, \mathcal{E})$ with the bornology $\mathcal B$ of
bounded subsets, we extend the coarse structure $\mathcal E$ from $X\times X$
to the natural coarse structure on $(\mathcal B \backslash \lbrace
\emptyset\rbrace)\times (\mathcal B \backslash \lbrace \emptyset\rbrace)$ and
say that a macro-uniform mapping $f: (\mathcal B \backslash \lbrace
\emptyset\rbrace)\rightarrow X$ (resp. $f: [ X]^2 \rightarrow X$) is a selector
(resp. 2-selector) of $(X, \mathcal{E})$ if $f(A)\in A$ for each $A\in \mathcal
B\setminus \lbrace\emptyset\rbrace$ (resp. $A \in [X]^2 )$. We prove that a
discrete coarse space $(X, \mathcal{E})$ admits a selector if and only if $(X,
\mathcal{E})$ admits a 2-selector if and only if there exists a linear order
$\leq$ on $X$ such that the family of intervals $\lbrace [a, b]: a,b\in X, \
a\leq b \}$ is a base for the bornology $\mathcal B$.
