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.
Via Kevin Goldstein, the Yankees have signed Preston Mattingly, Don’s son. The Dodgers gave him a $1M bonus as the 31st overall selection in the 2006, and he’s since gone on to hit .232/.276/.335 with 520 strikeouts and 99 walks in 1,846 minor league plate appearances. He’s never played above Single-A and had to move from shortstop to second base to left field to first base. We’re talking a total non-prospect here, but sheesh, can you believe Donnie Baseball’s kid is already 24? Preston’s not even his oldest.
