A corresponding move will be made on Friday before the Oakland A's series.
Mora was signed in the off-season to start after Mark Reynolds was traded to Baltimore, but due to a car accident during spring training and Ryan Roberts' emergence, Mora was only receiving one to two starts per week. He was mainly used as a pinch-hitter.
The two-time All-Star was batting .228 with no home runs and 16 RBI in 42 games.
His best years came with the Baltimore Orioles and it's no surprise that the 39-year-old was coming to the end of his career.
It will be interesting to see who the Diamondbacks decide to call up.
AZSnakePit.com reports that third baseman Cody Ransom is the likely candidate from AAA Reno. Sean Burroughs is another option.
However, if a trade is made in the near future, Ransom or whoever else is chosen might be in for a short stay.
