Minor Moves: Duff, Corona, Mattingly releasedBy
Via The NY Post & Josh Norris, the Yankees have released minor league RHP Grant Duff, IF Reegie Corona, and OF Preston Mattingly. Duff, 29, has thrown just 46.2 IP over the last two seasons while battling arm problems. He threw really hard and was one of the team’s better relief prospects back in the day. The 25-year-old Corona hasn’t played since breaking his arm in 2010. A no-hit, all-glove type, he managed to spend two full years on the 40-man roster and was even a Rule 5 Draft pick of the Mariners back in 2008. Never really understood that whole thing. The Yankees signed Mattingly — Don’s son — in January and he never played in an official game for them.
