On a 26-man roster they had a 5-man bench. Catcher, 2 OFs (one of Quinn/Haseley and Bruce if healthy), and 2 IFs/Utility types. I think Forsythe did have the inside track but thought they would do Forsythe and then one more. That one more could be Bohm though they could start with a 6 or 7 man bench. Probably 6 and go with 16 pitchers the first 2 weeks. They are allowed to have a 3rd catcher travel with the team so they seem less likely to use that roster spot.
I start with Bohm on the bench as one of the 6. In 2-4 weeks they make a decision. Injuries of course could play a role.
Have we also asked the question of whether any Phillies will opt out? Family member pre-existing conditions count. Will Trout play the whole season with his wife giving birth? Sean Doolittle's wife here in DC is immuno compromised. Will he play?
I suspect each team might have a few players who choose not to play. We'll know more when we see who reports next week. And of course a bunch of Phillies tested positive. There could be a few pitchers who are not ready to open the season simply because they are quarantining for a couple of weeks.
