Doesn't look like there is at least not in FA that is a reasonable add.

Probably just best to go with Ortiz for '26 and hope Made makes the same leap Chourio did and is ready for '27. Probably unlikely for Made to do that so realistically it is probably '28 for Made.
Trade market there really isn't anyone and no Rengifo is not an option. Probably just best to move Turang back to SS and move Ortiz back to 3B. I would prefer a trade for someone like Donovan but I doubt the Cardinals would trade him in the division.
