Diamondbacks general manager Dave Stewart said Tuesday the team will not add a catcher to the roster in large part due to the development of prospect Pete O'Brien, according to The Arizona Republic.
"I've decided that I'm not going to pursue another catcher," Stewart said. "I talked with my people and my coaching staff. They believe that O'Brien is going to be around sooner than later. If that does happen, there's no need to go out and get another guy.
"We would have had to trade somebody we didn't want to trade to make it happen. We're going to be patient and allow the progression of O'Brien to take place and stand pat on that."
Tuffy Gosewisch is the only catcher on the Diamondbacks' 40-man roster with major-league experience. Rule 5 selection Oscar Hernandez, who spent last season with the Rays' low Class-A affiliate, will also be in camp competing for a roster spot.
The Diamondbacks acquired O'Brien in a trade with the Yankees in July. The 24-year-old O'Brien hit a career-best 34 home runs in 2014. He has a .267/.319/.534/.853 slash line over three minor-league seasons.
