Mariners still trade France for an outfielder, and use the extra money to get an elite bullpen arm
This goes hand in hand with my first point. The Mariners trade Ty France for Max Kepler. When you pair that with the Luke Raley and Mitch Haniger for Robbie Ray trade, the Mariners have surprisingly not taken on any additional salary. As it stands right now, the Mariners payroll is around $121 million, possibly giving them around $19 million to work with. If the lineup looks something like these, there aren't many holes left.
C- Cal Raleigh 1B- Luke Raley 2B- Josh Rojas 3B- Luis Urias SS- JP Crawford LF- Haniger/Canzone CF- Julio RF- Max Kepler DH- Mitch Garver
Sure, you might think they could add a third baseman, but in this market, they are pretty limited. My thoughts are you ride with that team but go out and sign an elite reliever. I really like Robert Stephenson. He was absolutely dominant last year with the Rays, throwing 38 1/3 innings, with a 2.35 ERA, 14.1 K/9 and a crazy 1.9 BB/9. This would give you an elite, high leverage arm to pair with Matt Brash and Andres Munoz. Reynaldo Lopez got a 3-year deal, worth $30 million with Atlanta, and I think it might take something similar, but Stephenson was elite. That only adds about $10 million, giving you an additional $9 million in cap space that they could look to add some pieces (or more likely for John Stanton to pocket).
