1. Andre Jackson
Andre Jackson made his MLB debut during the 2021 season and pitched quite well for the Dodgers. Jackson was by no means an elite arm, but he came up into a situation that's tough to succeed in and managed to give the team some quality innings.
With that experience, it seemed like Jackson would get called upon more in 2022 to be that emergency arm to assist the pitching staff. That was not the case, as Ryan Pepiot got those chances more than any other young arm.
Jackson appeared in only four games for the Dodgers, throwing a total of 9.2 innings. All of those games came in September when the roster expanded and the team was just trying to keep other arms fresh. Jackson was good in those innings, but this isn't a good sign for his big-league future in LA.
His performance in Triple-A does not bode well for him, either. Jackson threw 75.2 innings for Oklahoma City in 2022, finishing with a 5.00 ERA and 1.705 WHIP.
The Dodgers have a lot of young arms that are both on the active roster and/or knocking on the door. There are only so many roster spots to give out, and at some point you're going to run out of minor-league options.
Unfortunately, that seems to be the fate for Jackson, as he's simply the odd man out heading into his age-27 season.
