The Diamondbacks released Melvin Mora, according to Enrique Rojas of ESPN Deportes (on Twitter in Spanish). Craig Grialou of 620 KTAR first reported the move (on Twitter).
Mora, 39, hit just .230/.246/.278 in 134 plate appearances this year while seeing time at third base almost exclusively. With Ryan Roberts having a big year, Mora was the odd man out and had to settle for limited action off the bench. Arizona signed him to a one-year deal worth $2MM in the offseason, and they'll still be on the hook for that salary the rest of the season.
