We'll know more today when the Option period ends.
I follow more on the SP side. Here was an article I found that was interesting. I've listed the T10SP and you can go read the details about them.

Last year, the Cardinals struck early and often to fill their needs. It is common for Boras to hold off signing SPs in order to get teams desperate. Cards chose to not go after the Top SPs and fill their needs with players who were affordable bargains.
I think the T4 will take some time to get signed. Flaherty is a mystery, to me. The bottom of the list will likely go quickly to get ahead of things, with the exception of Manaea... he could be lumped in with the T4 that take longer.
There are several Japanese options. If Sasaki gets posted, he is #1, then there are a variety of others.
Rangers had 3 guys I'm watching: Heaney, Lorenzen, and Urena.
For the non-Rangers fans:
Heaney is one CY is targeting with Eovaldi. Clubhouse veterans that CY and Bochy trust... mentor the younger guys... and of course central to the WS win.
Lorenzen is a personal favorite. He has been looking for a multi-year deal. He could end up in KC or Texas and could be "affordable" given multi-years.
Urena was once a ToTR type SP... had hip (IIRC) injury and struggled to return. He showed well for the Rangers and played the coveted role of "whatever you ask me to do." BP guy... moved to rotation... back to the BP. Could give you 3-4 IP out of the BP, or stretch out to a SP. I doubt he gives you 150 IP in '25, but on a multi-year deal, could find himself in the rotation and top that in '26.
