The Mariners have had quite a few players handle first base in year 1 of their rebuild. Jay Bruce, Edwin Encarnacion, Daniel Vogelbach, and Austin Nola have all spent significant time at the position.
But Bruce and Encarnacion are long gone, Vogelbach has struggled for 2 months, and Austin Nola doesn’t carry the thump needed to be the everyday option at the spot. Some have speculated that a move to first base for either Domingo Santana or Omar Narvaez could be an option moving forward, but they still need to learn the spot.
