Yeah I just don't see why they would prioritize positional flexibility or CF ability over a better bat. Merrifield's has been weak for four of the last five seasons. He makes up for it with his other qualities but those aren't the qualities the Phillies need.
Sosa matched him in both WAR and OPS+ last season.
I would think Senzel is a cheap one-year signing, with incentives and maybe an option. I don't know if he's the guy either but there are plenty of other candidates.
Still would like to see LHB who can play 3B too.
