Finally, we come to the bullpen which should be a strength of the Braves roster next season. Atlanta has postseason hero Tyler Matzek coming back from Tommy John surgery, added Aaron Bummer, Angel Perdomo, and (probably) Reynaldo Lopez, and brought back Joe Jimenez and Pierce Johnson. Once you factor in returning relief studs Raisel Iglesias and AJ Minter, the Braves' bullpen is incredibly deep at the moment which you love to see.
Unfortunately, that isn't great news for Dylan Lee. Even if you ignore the fact that Lee couldn't get healthy last year due to issues with his throwing shoulder, the Braves' bullpen depth poses an issue for Lee's future. Right now, the Braves already have lefties Minter, Matzek, Bummer, and with Perdomo inked to a split contract as well. That is a lot of competition for innings just among the southpaws.
Could the Braves opt to carry Lee in the bullpen? Sure, especially if he is fully healthy. Atlanta does tend to like to carry an extra reliever right out of spring training and Lee has a track record of production. However, with all of the arms the Braves have at their disposal, it wouldn't be surprising whatsoever if Lee finds himself without a big league roster spot or even with another organization in 2024.
