The Diamondbacks and Nationals are among several clubs that have expressed interest in free agent Aaron Heilman this winter, according to Jerry Crasnick of ESPN (via Twitter). After five straight years of 70-plus appearances out of the bullpen, Heilman is looking to become a starter.
Heilman, 32, posted a 4.50 ERA with 6.9 K/9 and 3.3 BB/9 for the D'Backs last season. Since he declined Arizona's arbitration offer, the club will not receive compensation if they lose the Type B free agent. Last month we learned that the Rockies and Pirates were interested in the right-hander as a reliever.
