No one is really pushing to replace either one so they should stick around. However, it's going to be hard to get this lineup more balanced (except at 2B if you add someone like Adam Frazier and add a veteran switch hitter behind the plate in Caratini). If you decline the TA option and make a trade for a left-handed MI that can play SS, I guess that would help the balance issue, though I don't know who that guy would be.
