The Seattle Mariners had a great deal of success with their relief corps, but adding proven options given the fungible nature of relievers never hurts.
Even if the Mariners have confidence that their relievers can replicate that success next year, there is still a major void in the bullpen. According to their depth chart on MLB.com, the Mariners do not have a single left handed reliever. That lack of a lefty reliever proved to make a difference in the postseason when Robbie Ray had his offering crushed by Yordan Alvarez to give the Astros a walk-off victory in Game One of the ALDS.
Fortunately, there is an option that can make a difference in free agency. Andrew Chafin is arguably the best left handed reliever in the market, someone who has been adept at shutting down hitters on either side, using his ability to generate grounders and excellent command to perform better than his stuff would seemingly indicate.
Chafin is someone that would be of interest for a team looking to win now and over the next few years. He will turn 33 years old in the middle of the 2023 campaign, and given how volatile relievers can be, it is fair to wonder how long he can continue his dominance. However, he is not showing any signs of slowing down and could be that missing piece in Seattle.
The Seattle Mariners need to add more balance to their bullpen. Andrew Chafin would give them a desperately needed shutdown lefty.
