ARLINGTON -- Assistant general manager Thad Levine has emerged as a candidate to be the D-backs' GM. Arizona dismissed Kevin Towers earlier this month and Tony La Russa, who heads the organization's baseball operations, is conducting a search for a replacement.
Former Rangers farm director Tim Purpura is also being considered. Once the GM of the Astros, Purpura is working for Texas as a special assistant in ballpark operations.
Levine is in his ninth season with the Rangers assisting GM Jon Daniels in all areas of Major League operations. Prior to that he spent six years with the Rockies.
The Rangers recently lost A.J. Preller, another key member of the front office, who left to become GM of the Padres. Don Welke, who was a special assistant, went with Preller.
