Diamondbacks' Juan Graterol: Designated for assignment

Graterol was designated for assignment by the Diamondbacks on Friday.

Analysis:

The Diamondbacks agreed to a deal with veteran catcher Chris Iannetta and subsequently designated Graterol for assignment. The 27-year-old catcher has only appeared in nine major league games over his 10-year professional career. He doesn't figure to serve as anything more than organization catching depth wherever he lands.
