The Arizona Diamondbacks have interviewed at least six coaches from their organization as they search for a new pitching coach.

The front office sat down with minor-league pitching coordinator Dan Carlson and rehab coordinator Brad Arnsberg, along with all four of their full-season affiliate pitching coaches -- Mike Parrott (Triple-A), Wellington Cepeda (Double-A), Gil Heredia (High-A) and Doug Bochtler (Low-A).

There are also a number of outside candidates for the position, including Gil Patterson, who has spent the past three seasons as the New York Yankees' minor-league pitching coordinator, and Garvin Alston, who just completed his first season in the same role with the Oakland Athletics.
