(Peoria, AZ)  --  Seattle Mariners right-handed pitcher Erasmo Ramirez is being traded to the Tampa Bay Rays for southpaw Mike Montgomery.  Ramirez, who's struggled over the past couple of seasons for the Mariners, was unable to win a spot in the starting rotation during spring training.  Montgomery, who was a first-round draft pick for Kansas City in 2008, hasn't yet pitched in the Majors.
