RHP ADAM WARREN

The Mariners had to give up the majority of their international slot money ($1.25 million) to get Adam Warren, but that’s still quite a bargain for a pitcher of his caliber.
In a deal that came as a major surprise, the Mariners landed a reliever who can do a bit of everything for them. Given his past as a starter, Warren is capable of giving the M’s multiple innings on occasion. He also has the ability to pitch in high-leverage situations late in ballgames, giving the M’s even more flexibility throughout their stacked bullpen.
Of the three rentals the M’s acquired this week, Warren seems to be the likeliest candidate to end up back with Seattle in the offseason. Depending on what the future holds for the Mariners in the upcoming free agency period, Warren could be given another opportunity to start in 2019.
Even if he only lasts three months, the Mariners still found an insane amount of value in this deal.
