I don't think they are there yet, but I did notice he has options (and not enough service time). Far too soon to just say that he's done. Can't really trade him for value.
But also why is he the problem but not Bohm?
Everyone in the line-up still has a positive WAR except for Kepler, Bohm and Marsh. Those guys are all scuffling but it's Harper and Turner who really have to step up. Casty is out-producing Harper and Stott is out-producing Turner (barely). That won't (or at least can't) last.
They can play Sosa in the OF more (against LHP) and they could also let Clemens play 3B once a week against RHP.
If things continue we can certainly say Dombrowski's off-season was a failure, at least in the line-up. He kept Bohm and did not configure a good OF by opting for a second LHB, with both that new player and the guy who got handed CF struggling (plus their insistence that they could both play everyday is incorrect).
I still don't see the Marsh trade as a failure in any way. The Phillies got to the World Series, won the NL East and have gotten 7.3 WAR from him in 2 1/2 seasons (and only as a 3/4-time player to boot), plus he's still cheap and controlled for three more years. Anyone else they might have traded O'Hoppe for probably wouldn't be on the team by now (i.e. the 2022 equivalent of Carlos Estevez, or a 1 1/2 season veteran OF. They also could have tried to get Soto in '22 but the team that did lost to us in the NLCS, and he would have cost a lot more than O'Hoppe).
