The Texas Rangers are trading right-handed reliever Rafael Montero to the Seattle Mariners in exchange for a pitching prospect and a player to be named later, sources told ESPN's Jeff Passan on Tuesday.
Montero, 30, appeared in 17 games this past season for Texas, compiling a 4.08 ERA to go with 8 saves.
The Rangers will receive 17-year-old Jose Corniell, a right-handed pitcher whom Seattle gave a $630,000 bonus in the last international signing period. The 6-3, 170-pound Corniell has a fastball that reaches the mid-90s and could bump even higher as his body fills out.
