The Rays' premise in getting rid of leading home-run hitter C.J. Cron last week was to create the opportunity to add a better bat. Either to upgrade at the first base / DH spot Cron shared or, better, to add a right-handed hitter with more positional versatility who can make the lineup better in different ways.
So, who?
Obviously, we don't know.
Realistically, as early as it is in the off-season, neither do the Rays.
They have money to spend, given the potential to field their current somewhat young and extremely cheap squad for around $32 million with only Kevin Kiermaier to make more than $5 million.
