The Cubs have already made one major bullpen acquisition this offseason, trading with the Royals for closer Wade Davis to fill the gap left by Aroldis Chapman. Wilson and Mike Montgomery would give the Cubs two lefties in the bullpen.
Wilson, 29, is under team control through the 2018 season. Over parts of five seasons in the majors, Wilson has a career 3.28 ERA with a 258/98 K/BB ratio in 258 innings. He doesn’t have much of a platoon split over his career and even showed a reverse split last season, suggesting that he might fit better in a full-inning role rather than being used as a lefty specialist.
