Seattle Mariners Holiday Wishlist: 3 Lefty Bullpen Weapons

The Seattle Mariners have a dire need for left-handed relievers, here are three arms that would improve the bullpen.

With the recent additions of hard-throwing right-handers Rafael Montero and Keynan Middleton, the Seattle Mariners’ glaring need for a few more left-handed options out of the bullpen became far more obvious. Out of the 16 relievers currently on the 40-man roster, only two are southpaws; Anthony Misiewicz and Aaron Fletcher.

This need is more than likely to be filled sooner rather than later by general manager Jerry Dipoto, as he has stated the plan is to bring in a multitude of new relief arms this offseason. Dipoto has been busy adding pitchers after a very rough 2020 performance from the pen, but they have all been right-handers. It would be ideal if Seattle can go out and acquire a high-leverage left-handed weapon to shake up the balance of the bullpen.

The 40-man roster is currently full, and Phillip Ervin was designated for assignment to make room for Keynan Middleton. The next to go will very likely be one of the 16 bullpen arms, forcing more of an even split for manager Scott Servais to choose from.

Based on his track record, one would have to expect Dipoto to bring in multiple new lefties over the course of the offseason, ranging possibly from big names to minor league signings or waiver claims. Here are the three best left-handed bullpen arms on the free-agent market that would bring a major change to the Mariners ‘pen in 2021.
