More former Colorado Rockies are joining the ballclub this spring in instructional roles with the organization. Eric Young and Pedro Astacio were hired yesterday as guest instructors. Young played for the Rockies from 1993 to 1997. He’ll work with position players on basestealing and bunting. Astacio, who ironically was acquired in a trade for Young and pitched in Denver from 1997 to 2001, will work with the pitchers.
