If the Cubs were to sign a right-handed pitcher to fill in for Codi Heuer’s pending retirement, they might have picked Chris Martin. The former Rockies reliever has spent six seasons in the Major Leagues, including stints with the Rockies, Rangers, and Braves. His strikeout-to-walk ratio is 6.45. The Cubs need bullpen reinforcements, but Martin is the right fit to replace Codi.
