Herrera is out of minor-league options as he prepares to compete for the backup catcher job in spring training, Alex Weiner of Arizona Sports reports.
That Herrera is out of options gives him an advantage in the quest to back up primary catcher Gabriel Moreno. Herrera's advanced defense is another edge over Adrian Del Castillo, who crushed the ball during his MLB debut last season. It's likely the Diamondbacks have Del Castillo head back to Triple-A Reno to hone his defense, while Herrera, who has earned trust in the Arizona clubhouse, grabs a roster spot for Opening Day.
