I don't have any worries about the pen. We have Zas coming back soon along with Yoho and McGee. I think we will see Crow and Holub get some pen innings as well. You can also see some of the young starters get some innings there to keep their workload in check.
To me our biggest weakness is the left side of the infield.
#4 - Jesus Made - SS
#48 - Luis Pena - SS / 2B
#51 - Cooper Pratt - SS
#64 - Brandon Sprout - RHP
#66 - Jett Williams - SS / 2B
#88 - Logan Henderson - RHP
#96 - Bishop Letson - RHP
#99 - Luis Lara - OF
We will see McGee, Crow and Yoho to get through the regular season for right handers in the pen. In the playoffs, you will likely see Patrick and maybe even Sprout. I don't see it as a need at the moment.
Projected for a .700 OPS with a little bit of power. It seems like the projections do not like his defense.
This seems like a better 40 man roster option than Peralta.
