Is there a world in which Dylan Covey actually adds enough value this season to justify losing Noah Song?
Covey looks like a "ROOGY" - RHP, one-out guy, can be effective against RH hitters. But lefties just murder him, and with the three-batter rule now in force, if you go to Covey to get a RH hitter out, and he doesn't get the out, and he's now facing a LH hitter (and you cannot take Covey out because or the three-batter rule), he just gets clobbered.
The three-batter rule makes it very hard to keep a relief pitcher who is effective with the platoon split, and horrible without it. Covey's an example. He's effective against RH bats, but half the time, he's faced LH hitters (49 out of 100 PA), and they have killed him. In a mop-up role, he's going to give up runs, and he has no future here.
Song might well be just as bad in 2023, in the mop-up role. But Song could have serious value in 2024 and beyond.
Thomson is, rightly, focused on 2023. That's his job, as the manager.
Dombrowski's job as club President is to balance 2023 needs against the organization's future. There is, inevitably, some tension between the short-term (2023) and longer-term (2024 and after) needs of the organization - and thus, some potential tension between the manager and the President ( At the end of the day, the roster decision is Dombrowski's, not Thomson's.
