Candidates for last spot on the roster:
Cave
Pache
Wilson
Clemens

Dahl
Castro (probably more insurance for Sosa but he is still around)

Anybody else? None of them really make a good 26th man. The bench is very right-handed so the lefties on the 40 (Cave, Clemens, Hall) probably have an advantage. Pache might have the most value and is out of options. Dahl is not on the 40 so his status might depend on his minor league opt-out date. Of the 3 lefties on the 40, Cave plays the best OF defense, Clemens could spell Bohm from the left side at 3B, and Hall is the best hitter who has nowhere to start.
I'd probably rank them Cave then Pache then Clemens on likelihood to make the team. Maybe an injury will delay the decision for a second player. I'm really not expecting Dahl to be any good but I guess he is the most talented. Wilson would make more sense without Merrifield. Bottom line is it probably doesn't matter and the decision likely will depend in part on how they manage the 40 and what they really feel about Pache.
