You dont buy insurance you dont need.
Here is the depth chart if you sign Franco:
Kieboom
Castro moving to third and playing Harrison at second
Castro moving to third and playing Garcia at second
Making a trade for a third baseman
Drew Mendoza
Franco
Wow. I hope all those alternatives don’t destroy Kieboom’s confidence.
Garcia could use time in the minors to improve his hitting. If Harrison plays every day then who takes his place on the bench. You sign Franco or some equivalent player to a minor league deal and then put them in Rochester in case needed due to bad performance or injuries. If they have no depth at Triple A to call up you will be the first one complaining.
