The Mariners have elected to trade relievers Roenis Elias and Hunter Strickland to the Washington Nationals in exchange for Top 30 LHP Prospects Taylor Guilbeau and Aaron Fletcher. They also received RHP Elvis Alvarado in the Elias deal.
Guilbeau, 26, is unequivocally the anchor of this deal for Seattle. Ranked the 15th best prospect in the Nationals system by MLBPipeline.com, and 14th best by Baseball America, Guilbeau is a lefty-specialist coming out of the bullpen.
A two-pitch southpaw, Guilbeau has generally been regarded as a LOOGY specialist in the past, though his reverse splits this year suggest otherwise.
