Hurdle couldn't previously speak to the Pirates because Texas advanced to the World Series.
The 53-year-old Hurdle had a 534-625 record as the Colorado manager from 2002 until May 30, 2009, when he was fired and replaced by former Pirates manager Jim Tracy following an 18-28 start. Hurdle previously was Colorado's hitting coach.
The Rockies won 14 of their final 15 games under Hurdle to reach the postseason in 2007, then won seven consecutive playoff games before being swept by the Red Sox in the World Series.
The Pirates last interviewed a candidate on Oct. 14, when they talked to Braves bench coach Carlos Tosca.
