SEATTLE (AP) — The Seattle Mariners have bolstered their bullpen by acquiring right-handed reliever Rafael Montero from the Texas Rangers. Montero was the Rangers closer for most of last season after Jose Leclerc was sidelined for the season due to a right shoulder injury after just two appearances. Montero appeared in 17 games and was 8-for-8 in save situations. Montero was 0-1 with a 4.08 ERA. Seattle sent 17-year-old right-handed pitching prospect José Corniell and a player to be named to the Rangers for Montero.
