This year’s Mariners roster is about as set heading into Spring Training as it’s been in years, maybe ever, with twelve players as written in ink as you can be at this point. You’ve got the starting nine in Cal Raleigh, Ty France, Jorge Polanco, J.P. Crawford, Josh Rojas, Luke Raley, Julio Rodríguez, Mitch Haniger, and Mitch Garver. Then there are Rojas and Raley’s platoon-mates in Luis Urías and Dylan Moore and the backup catcher, Seby Zavala.
That leaves just one roster spot. Given the construction of this roster, the thing that makes the most sense for that spot is a lefty outfielder.
