Inside Boston’s depth chart, the expected internal lefty options include Aroldis Chapman (the closer), Jovani Moran, and Tyler Samaniego. The Red Sox are understood to be weighing additional left-handed relief to complement that group, potentially through free agency or a strategic move in the coming weeks.
Danny Coulombe stands out as a strong option among veteran relievers, having posted a 2.30 ERA across 43 innings last season with the Twins and Rangers. His earlier 2025 performance, including a 1.16 ERA in 31 innings with Minnesota, helped elevate his profile as a reliable, low-variance lefty out of the bullpen.
Industry observers have noted that while Coulombe could be the best available left-handed reliever on the market, he may be seeking a major-league contract given his age and recent track record. Boston, meanwhile, could pursue alternatives such as a waiver claim or a smaller trade to bolster depth without sacrificing long-term flexibility.
Overall, the Red Sox appear inclined to add left-handed bullpen depth, but likely on their terms. They possess a deep pitching staff and will weigh the cost and impact of adding another southpaw against internal development and competition among their right-handed bullpen options.
If Boston proceeds with an addition, the goal would be to fortify late-inning options and maintain balance in the bullpen, while avoiding disruption to the club’s ongoing plans for pitching depth and development. The coming weeks will determine whether a new lefty reliever lands in Boston or the club opts for an alternative path to address this need.
