Taking a look at all three of these guys for the setup role is a good problem to have for the team as each comes with an impressive resume. If we take a look at their ERA on the season Baez holds a 1.94 mark, Morrow holds a 2.55, and Fields holds a 2.68. However, as of late, it has been Baez who has been giving up the most runs as he managed a 3.38 ERA in August.
Baez was once thought of to be the definite setup man, but as Morrow and Fields have shown their worth, he has fallen out of the spot.
