Last season, the Chicago Cubs had several left-handed relief options out of the bullpen. Travis Wood, Aroldis Chapman, Mike Montgomery, Clayton Richard and Rob Zastryzny all got the ball in various situations.
But opening 2017, the Cubs carried just one left-handed reliever in Montgomery, who lost out on the final spot in the rotation to Brett Anderson. Chapman went back to the Yankees on a mega-deal, Wood headed to the Kansas City Royals and Richard signed with the Padres.
