My guess is the plan is to start Cavalli at Rochester and see what happens. At best, 2025 is a year where he'll throw 100-150 innings and position himself for a rotation spot in 2026.
If they are thinking about Ogasawara as a starter then things get a bit interesting with Gore, Irvin, Parker, Williams, Soroka, Herz, and Ogasawara battling for 5 slots. Gore and Irvin are locks, probably Williams too. Herz should be a lock given how he pitched in the 2nd half last year.
Maybe Rizzo has a trade in mind for a 3B?
